Calibration and adjustment of a pH electrode

Why do you have to calibrate? The pH value of an aqueous solution is determined with pH measuring instruments, also known as pH meters. The accuracy of the pH measurement depends on the calibration and adjustment. The adjustment is the setting of the pH meter to the data of the pH electrode (slope and zero point) determined by calibration. Therefore, regular calibration is very useful.more
