Wine Analysis pH Benchtop Meter
HI 2222 is the only pH meter on the market today that allows for automatic pH calibration at pH 3 and pH 7. With the dedicated 3.00 pH buffer for wine calibration in the wine pH range, any error due to calibration will be minimized. The HI 2222’s Calibration Check™ diagnostics along with the included HI 1048P clogging resistant pH electode further enhances measurement accuracy.
This wine analysis instrument also features logging of up to 100 samples, GLP (Good Laboratory Practice) capability, and a USB interface for the transfer of data to a PC.
In the process of wine making, most pH measurements are made in the must. A pH electrode gets dirty quickly when measuring the pH of must because sediments build up on both the pH measuring bulb and pH electrode junction. This becomes a big problem during the actual pH measurement if the electrode has not been properly cleaned. A dirty pH electrode can give results that are up to 0.5 pH inaccurate — even after a pH calibration has just been performed.
Conventional pH meters do not warn the user when the pH electrode is dirty. A common example of this occurs just after calibrating the instrument — the pH electrode is immersed into the pH 7 buffer and the reading is lower than expected (pH 6.8 or 6.9 instead of 7.0). HI 2222 uses HANNA ’s unique technology to detect when the electrode is dirty and gives a warning during calibration.
It is important to properly clean the pH electrode prior to use. A proper cleaning of the electrode must be done with appropriate cleaning solutions in order to remove all the deposits on the sensitive bulb and junction. HI 70635 (wine deposits removal) and HI 70636 (wine stain removal) are tailored made cleaning solutions that remove deposits from your pH electrode to guarantee accurate calibrations for stable, repeatable measurements and long electrode life. HANNA is the only manufacturer to offer tailor made cleaning solutions for winemaking.
