CALIBRATION For best accuracy, it is recommended to calibrate the instrument frequently. In addition a pH calibration should be performed: a) Whenever the pH electrode or the batteries are replaced b) At least once a month c) After testing aggressive chemicals d) When extreme accuracy is required pH • pH calibration is now complete. Replace the trimmer cover and tighten it to ensure a proper seal against water and humidity ingress. PREPARATION Pour small quantities of pH 7.01 and pH 4.01 (or pH 10.
pH VALUES AT VARIOUS TEMPERATURES Temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions. For pH calibration, please refer to the following chart.
