The factors affecting the stability and accuracy of acidity meter were analyzed. These factors were as follows:glass electrode contamination,acidity meter calibration or calibration errors before use,uneven sample solution, acidity meter temperature settings were not consistent with the sample solution temperature. These solution methods to solve the problems of accuracy and stability were put forward.
