If the crystals remain or if the electrode is coated with oil or grease, rinse electrode with methyl alcohol and then with distilled water. 2. If deposits remain, soak in 1% HCl for 5 minutes followed by 1% NaOH for 5 minutes. 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 ...
WebMay 9, 2012 · Most pH meters are set up to perform 2-point calibrations using a pair of the three built-in calibration points - usually pH 4.00, 7.01 and 10.01 - depending on what you’ll be measuring. As brewers and winemakers, we deal with acidic solutions rather than basic ones, so it is appropriate to calibrate your meter using the 7.01 and 4.00 points.
