This is a set of storage, cleaning and calibration solutions designed to extend the life of the pH meter electrode.
The included buffer solutions pH 4.01 and pH 7.01 is normally in the right range for calibrating digital pH meters used in brewing.
If the pH meter only has one calibration point, you should use the buffer that is closest to the normal measurement range.
Included:
Buffer Solution pH 4.01, 230 ml
Buffer Solution pH 7.01, 230 ml
Cleaning Solution for Electrodes, 230 ml
PH electrode storage solution, 230 ml
