The highly advanced HI 222 pH/ORP/Temperature bench meter is the centerpiece of a complete kit ideal for performing highly accurate pH measurements in winemaking applications. Featuring automatic buffer recognition at pH 7 and 3, this meter is designed to calibrate to the proper pH range from 2.5 to 3.5pH (depending on the type of grape and/or wine) with an accuracy of ±0.002 pH.

In the process of making wine, most pH measurements are taken at the must stage. Measuring in must is a particularly challenging application for common pH electrodes. Sediments from the must coat the electrode’s measurement surfaces and will quickly hamper performance without frequent cleaning. For this reason, Hanna introduced an electrode that resists the sensor clogging effects of wine musts.

As a leading electrode manufacturer we have found that simply rinsing the electrode with common general purpose cleaning solution is not effective. In order to completely remove the deposits, application specific solutions must be used. We developed deposit removal and stain removal solutions tailor made for winemaking. These cleaning solutions remove all deposits from your pH electrode and guarantee that your measurements are always accurate and that your pH electrode will last a long time.
