ABSTRACT:
A system and method for checking the concentration of an electrolyte in a solution utilizing ion-selective electrodes for sequentially measuring potential levels of a sample solution and a correction solution at selected time intervals. The potential levels of the positive and negative ions in the sample and corrective solutions are then compared with a standard potential level for the correction solution. A procedure determines if an abnormal deviation in the sample solution exists and if this abnormal deviation is caused by the actual concentration of electrolytes in the sample solution or if the abnmormality is caused by an error in measurement. An alarm is sounded to indicate that the abnormality exists and the cause of the abnormality.
