WebNov 12, 2024 · The reference electrolyte, which is neutral pH, 3.0M KCl for the pHionics instruments and most of the industry. As soon as the electrolyte is either depleted or contaminated, the sensor loses a stable reference and cannot hold calibration. WebUsers of glass pH electrodes should also be aware of alkaline and acid errors that limit the pH range over which effective measurements can be made. At very high pH, generally > 10, most glass electrodes become responsive to both H + and Na +, with the measured pH being lower than actual. At low pH, typically < 1, glass membranes are ...
