Details

The HI2020W wine pH edge meter (kit) includes the popular HI2020 edge meter that offers an innovative slim design. The edge meter is only 0.5" thick yet rich in features to meet the needs of a wide range of customers. The HI2020W wine pH edge meter (kit) also includes a wine-specific pH electrode that is resistant to clogging, as well as all required solutions, including a specific cleaning solution for wine pH electrodes. The HI2020W wine pH meter (kit) can be upgraded at any time with additional probes to measure conductivity or dissolved oxygen.

pH CAL CHECK ™

The edge alerts the user to possible problems during the pH calibration process. By observing the voltages generated when calibrating for at least two points, the edge will indicate if the probe needs to be cleaned or if the intermediate memory is contaminated. After calibration, the edge provides indicators for both the overall probe status and response time.

Wine electrode to prevent obstruction of CPS.

pH electrode HI10480 wine with CPS sleeve Junction

CPS ™ (Clogging Prevention System) is an innovation in electrode technology. Conventional pH electrodes use ceramic junctions that quickly clog when used in wine. When the junction clogs, the electrode does not function. CPS ™ technology uses ground glass porosity along with a PTFE sleeve to prevent junction clogging. The ground glass allows for adequate liquid flow, while the PTFE sleeve repels dirt. As a result, pH electrodes with CPS ™ stay fresh up to 20 times longer than conventional electrodes.

The importance of pH in winemaking

pH in wine

The pH of wine is important to determine, as 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 the 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.

Most wines optimally have a pH between 2.9 and 4.0, with different values depending on the type of wine. Values above pH 4.0 indicate that the wine can spoil quickly and be chemically unstable. Lower pH values allow the wine to stay fresher for longer and preserve its original color and flavor. It is more likely to breed bacteria and be suitable for high pH drinking wine. For finished white wines, the ideal pH is between pH 3.00 and pH 3.30, while the ideal final pH for red wine is between pH 3.40 and pH 3.50. The optimal pH before the fermentation process is between pH 2.9 and pH 4.0. Therefore, the pH of wine not only affects the color of the wine but also oxidation, yeast fermentation, protein stability, and bacterial growth and fermentation.

The HI2020W wine pH meter (kit) includes all the necessary materials to determine the pH of wine must and juice with precision. The meter supplied with the HI2020W is the multi-parameter edge, HI2020. The HI2020 is an advanced meter that is rich in features including the use of digital electrodes that can be swapped at any time to switch to a different parameter, built-in rechargeable battery, two USB ports, data logging, automatic calibration, GLP (Good Laboratory Practice) data for the latest calibrations, and Hanna's exclusive calibration check function that alerts the user to potential problems during calibration, including when it is necessary to clean the electrode and when the intermediate memory may be contaminated. The HI 2020 is a versatile meter that can be used as a workbench, portable, and even a wall mount to save space. The HI2020 is one of the most advanced meters available, but the most important aspect in pH measurement is having the correct sensor for the application.

pH electrode wine

The HI2020W pH meter (kit) is packaged with the HI10480 instead of the normally supplied HI11310. The HI10480 is a specially designed pH electrode that is resistant to obstruction from solids present in grape juice and must. This double junction, refillable pH electrode has a unique frosted glass junction and PTFE sleeve to provide unparalleled performance for the wine industry. A standard pH electrode will have a ceramic junction that can easily be obstructed by solids. When this happens, pH readings will be erratic and drift over time before stabilizing at the actual pH value of the wine sample. The HI10480 with CPS technology will prevent obstruction crossover. The HI10480 is a digital electrode that when used with the HI2020 edge will change the default buffer from pH 4.01 and 7.01 to pH 3.00 and 7.01.

magnetic stirrer

The HI2020W 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 homogeneous in consistency and temperature. Stirring the sample also helps to accelerate the response time of a sensor in achieving a stable reading.

pH solutions

The HI2020W wine pH kit also includes all solutions for calibration and maintenance. To ensure the highest precision in measurement, it is important to calibrate with buffers around the expected reading. Since wine pH is below pH 4.01, it is important to calibrate at a lower pH value. For calibration, the kit includes HI5003 pH 3.00 and technical calibration buffer HI5007 pH 7.01. Each NIST buffer bottle is supplied with a certificate of analysis that includes the batch number, expiration date, and reference materials used in production.

Cleaning solution

For the maintenance of the HI70635L wine storage solution and the electrode storage solution HI70300L cleaning. When the message "clean electrode" appears during the calibration of the HI2020 edge or there is a poor probe status (i.e., less than 30%) then soak the HI10480 in the cleaning solution for 15 minutes to clean the deposits from the glass surface. After cleaning, the probe should be rinsed with purified water and then soaked in the storage solution for 2-3 hours. The electrode storage solution is also used when the electrode is not in use. Place a small amount in the storage cap or in a beaker to keep the electrode properly hydrated.
