Internal clock date to keep track of different time-dependent functions (calibration, timestamp,calibration time out). 3 feet probe cables for extra flexibility when testing. Care and Use pH meters usually start performing poorly because of problems with the probe. The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction. Sensing Bulb The glass bulb loses sensitivity with use and will eventually fail. This is true of all pH probes. Reference Junction The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH electrode will no longer function. You can extend the life of your pH electrode in the following ways. Storage To minimize clogging the pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water. This will damage the sensitivity of the probe. The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage. Cleaning and Maitenance Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking your electrode in cleaning solution. Also: Inspect the electotrode for damage or scratches, if present replace the electrode. Inspect the cable.  The connection cable and insulation must be intact. Connectors should be clean and dry. Rinse off salt deposits with water or DI water. Calibration The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO Plus pH meter accurate. Also, calibrate after cleaning or a long period of storage. Specifications: pH Range: -2.00 to 20.00 pH / -2.000 to 20.000 pH ORP Range: ±2000.0 mV Temp.

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.

This rugged, compact electronic meter provides direct, simultaneous, and highly accurate readings of two of the most critical factors in water analysis. Built for reliable field use, the TRACER allows you to quickly check water status for applications across environmental science, pool and spa maintenance, agriculture, and industrial water treatment. Knowing your exact pH and temperature profile is essential for achieving consistent quality and compliance.   Key Measurements The pH TRACER measures two essential factors critical to water quality:pHTemperature   Features & Specifications Test Factors Range Resolution Accuracy pH 0.00 to 14.00 pH 0.01 pH ±0.01 pH Temperature 32° to 149°F (0 to 65°C) 0.1°F/°C ±1.8°F/°C   Additional Features: Simultaneous pH and Temperature display. 15-reading memory storage. Easy-to-replace flat surface electrode. Understanding Your Measurements Following the structure of the BrewLab Pro kit, here is a detailed breakdown of why these two measurements are vital for water quality control:   pH The chemistry of virtually any water-based system is complex, and the pH level is the single most critical factor that affects countless processes—from chemical reaction rates and nutrient solubility to corrosion and biological activity. In order to consistently achieve optimal quality, compliance, and product consistency, the pH of the sample must be monitored with high resolution and accuracy. The TRACER provides the precision needed for critical decision-making.   Temperature Temperature has a profound, often overlooked, impact on chemical measurements and system stability. Specifically, pH measurements are temperature-dependent, which is why the TRACER automatically utilizes Automatic Temperature Compensation (ATC) to ensure your pH readings are accurate regardless of the sample's temperature. Accurate temperature monitoring is also essential in maintaining ideal conditions for microbial growth, ensuring proper sterilization, and maximizing the effectiveness of chemical reactions across all industrial and environmental applications.
