The HI84500-55 is a 120 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84500 in determining the exact concentration of sulfur dioxide. The pump calibration procedure should be performed anytime the titrant or ORP electrode is replaced. Standardized solution Clearly marked expiration date and lot number Air tight bottle with tamper-proof seal to ensure quality Analysis of sulfur dioxide in wine, as performed on the HI84500 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is performed with HI84500-55 pump calibration solution. The pump calibration procedure involves the analysis of a known volume of a known solution. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or ORP electrode is replaced.

edge® digital wine pH meter kit delivers precision while offering simplicity and versatility in a sleek design. Upgrade to the Hanna edge® wine pH kit for professional winemakers. The HI2020W allows you to add a conductivity probe and a dissolved oxygen probe to give you full versatility. Fast results, ultra-accurate, hassle-free analysis. Complete meter kit for measuring pH in wine. CAL Check™ feature ensures the accuracy of the meter. Great for professional and home winemakers. The Importance of pH in Wine Making The pH of wine is important to determine because it will affect the quality of the final product in terms of taste, color, oxidation, chemical stability and other factors. Generally in winemaking, the higher the pH reading, the lower amount of acidity in the wine. Three important factors in determining the pH of wine include the ratio of malic acid to tartaric acid, the amount of potassium, and the total amount of acid present.   The edge HI2020W wine pH meter kit includes all the necessary supplies to determine the pH of wine must and juice accurately. The meter supplied with the HI2020W is the multiparameter edge, HI2020. The HI2020 is an advanced meter that is rich in features including using digital electrodes that can be swapped out anytime to switch to a different parameter, built in rechargeable battery, two USB ports, datalogging, automatic calibration, GLP (good laboratory practice) data for last calibrations, and Hanna’s exclusive calibration check feature that will alert the user to potential problems during calibration including when to clean the electrode and when the buffer might be contaminated. The HI2020 is a versatile pH meter for winemaking that be used as a benchtop, portable and even a wall mount to conserve space. The HI2020 is one of the most advanced meters available but  the most important aspect in measuring pH is having the correct sensor for the application.   The HI2020W wine kit is packaged with the HI10480 (MT620Z) in place of the normally supplied HI11310. The HI10480 is a specially designed pH electrode that is resistant to clogging to the solids found in grape juice and must. This double junction, refillable pH electrode has a unique ground glass junction and PTFE sleeve to provide unsurpassed performance for the wine industry.  A standard pH electrode will have a ceramic junction that can be easily clogged by solids. When this happens the pH readings will be erratic and drift over time before stabilizing on the actual pH value of the wine sample. The HI10480 with CPS technology will prevent the junction from clogging. The HI10480 is a digital electrode that when used with the edge HI2020 will change the default buffer set from pH 4.01and  7.01 to  pH 3.00 and 7.01.   The edge HI2020W (MT620) wine pH meter (kit) includes the HI180-1 compact magnetic mini-stirrer. The use of a magnetic stirrer allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time of a sensor in achieving a stable reading.    The edge HI2020W wine pH kit also includes all the solutions for calibration and maintenance. In order to ensure the highest of accuracy in measurement it is important to bracket the calibration buffers around the expected reading. Since the pH of wine is less than pH 4.01 it is important to calibrate at a lower pH value. For calibration the kit includes the HI5003 (MT611) pH 3.00 and the HI5007 pH 7.01 technical calibration buffer. Each bottle of buffer NIST traceable is supplied with a certificate of analysis that includes lot number, expiration date and reference materials used in production.    For maintenance the The HI70635L cleaning solution for wine deposits and the HI70300L (MT631)electrode storage solution. When the “clean electrode” message is displayed during the calibration of the HI2020 edge or there is a poor probe condition (i.e. less than 30%) then soak the HI10480 in the cleaning solution for 15 minutes to clean any deposits from the glass surface. After cleaning the probe should be rinsed with purified water and then allowed to soak in the storage solution for 2-3 hours. The electrode storage solution is also used when the electrode is not in use. Either place a small amount into the storage cap or into a beaker in order to maintain a properly hydrated electrode.   Importance of maintaining a clean pH electrode The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.   The Cleaning Solution Series ensures maximum efficiency and accuracy of your sensors when used for its designated application. Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. Benchtop Portable, or Wall Mount versatile pH meter Swappable digital electrodes Built in rechargeable battery Two USB ports Automatic calibration,and data logging for GLP data Large easy to read display   NOTE: The shape of the stir plate may differ from what is shown in the example photo. The function and approximate size will be the same, but it may be round or square depending on what the supplier has in stock.

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode. Clogging Prevention System (CPS™) Technology Refillable Electrode Double Junction Design Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.   The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.   General Purpose Glass Formulation General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.   Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.   CPS Sleeve Junction Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.   Double Junction Reference A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.   Refillable The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.   Glass Electrode Body The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.   BNC Connector The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable. Single Junction Versus Double Junction pH Electrodes   Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.   Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction.

The instrument is based on a state-of-the-art optical system which guarantees accurate results, assures long term stability, and minimizes stray light and color interferences. It also compensates for variations in intensity of the lamp, although proper calibration ensures measurements are fully validated, comparable, and in compliance with regulatory requirements. The 25 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements.   Features at-a-glance   AMCO AEPA-1 Primary Turbidity Standard - The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.   Calibration – A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 10, 100, and 500 NTU) standards. Calibration points can be modified if user-prepared standards are used.   Fast Tracker™ - For users taking measurements throughout the winemaking process, the HI83749 is equipped with Fast Tracker™ - Tag Identi˜fication System (T.I.S.) that makes data collecting and management simpler than ever. Fast Tracker™ allows winemakers to record the time and location of a speci˜fic measurement or series of measurements using iButton™ tags on specific tanks for quick and easy readings. Each iButton® tag contains a computer chip with a unique identi˜cation code encased in stainless steel.   GLP Data – The HI83749 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.   Data Logging – Up to 200 measurements can be stored in the internal memory and recalled at any time.   Data Transfer – For further storage or analysis options, logged data can be downloaded to a Windows compatible PC using the RS232 or USB port and the HI92000 software.   Backlit Display – A backlit LCD display provides an easy to understand, user-friendly interface. Displayed codes guide the user step-by-step through routine operation and calibration.   Significance of Use Unrefined wine is quite turbid and hazy from suspended solids produced during fermentation. The unrefined wine is treated with fining agents to reduce cloudiness. This cloudiness is what winemakers refer to as protein haze, or haze for short. Thaumatin-like proteins (TLPs) and chitinases are the primary grape proteins responsible for haze formation. These positively charged proteins degenerate and stick together, resulting in undesirable flocculent clouds and visible haziness.   The prevention of protein haze or deposit in bottled white wines is a universal concern and often a wine needs to be stabilized before bottling. One commonly used stabilization agent is bentonite. Bentonite is a volcanic clay earth type fining agent (like kaolin) that acts as a wine stabilizer. It improves the clarity of wine but has also negative aspects because of the volume of lees formed, reduction of tannin and color. Since there are different types and qualities of bentonite with different capacity of protein removal, it is important to make laboratory trials with the same lot and wetting degree of the bentonite as that will be used in the cellar.   Protein stabilization is normally not a problem in bottled red wines because of the relatively high concentration of phenols that binds and precipitates with the unstable proteins before bottling. Often bentonite is added to red wines at a level of about 12 g/hL (1 lb/1000 gal), reducing colloidal suspended particles thus improving membrane filterability.   Wines with low phenols contents, such as rose, light reds and whites should be checked for protein stability before bottling. Hanna offers a rapid test to verify the risk of future protein haze formation. If protein instability is detected, a next test can help defining the right amount of bentonite to be added for improving protein stability. It is important not to overdose bentonite, avoiding stripping wine flavour, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability results in a reduction of costs.   Winemakers can determine the initial turbidity of the unrefined wine with the HI83749 turbidity measurement instrument. After taking a turbidity reading the pre-made HI83749-20 Bentocheck Solution is added to the wine sample. A second turbidity measurement is taken. If the second turbidity reading is less than the initial turbidity reading plus 2 NTU, the wine can be considered stable. Otherwise a fining trial can be performed to determine the amount of bentonite that must be added to stabilize the wine. Principal of Operation To measure turbidity the HI83749 passes a light beam through the sample that is scattered in all directions. The intensity and pattern of the scattered light is affected by many variables, such as wavelength of the incident light, particle size and shape, refractive index, and color. The optical system of the HI83749 includes a tungsten fi˜lament lamp, a scattered light detector (90°) and a transmitted light detector (180°).   The HI83749 features a powerful microprocessor that calculates the NTU value from the signals that reach the two detectors. An effective algorithm is used to correct and compensate for any color interferences. The optical system and measuring technique also compensate for fluctuations in lamp intensity, minimizing the need for frequent calibration. The HI83749-11 AMCO AEPA-1 standards ensure that measurements are traceable to primary reference materials. These standards are used for calibration and performance verification of the turbidity meter.   Supplied with Certificate of Analysis • Lot number • Expiration date • Standard value @ 25 °C • Reference meter NIST traceable   Provided storage containers • Light tight • Protects from accidental breakage   Can log and transfer up to 200 measurements and is equipped with Fast Tracker Tag Identification System (TIS) that makes data collecting and management simple by recording time and location with the touch of a button, a two, three, or four- point turbidity calibration can be performed using the supplied standards, features a backlit LCD display with a user-friendly interface which has user step by step help through routine use and calibration

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode. Clogging Prevention System (CPS™) Technology Refillable Electrode Double Junction Design Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.   The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.   General Purpose Glass Formulation General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.   Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.   CPS Sleeve Junction Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.   Double Junction Reference A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.   Refillable The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.   Glass Electrode Body The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.   BNC Connector The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.   Single Junction Versus Double Junction pH Electrodes Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.   Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction. Able to measure samples 0 - 80C Glass body, refillable sleeve junction PH electrode with a BNC connector Features a double junction reference with Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass Ideal for wine must and juice due to high solid content that would clog a standard general purpose PH Electrode
