Page 28: Interpreting Calibration Curves
Interpreting Calibration Curves This depends on the chemical composition and temperature of the samples that are measured regularly and can strongly affect how the efficacy of the electrode slope declines due to aging of the electrode’s glass membrane. This information therefore provides clues that have to be interpreted taking into account the true situation. -
Page 29: Temperature Compensation
Temperature Compensation Note: The temperature is compensated automatically only if an ATC probe is connected. Temperature has two major effects on the results: 1. Temperature affects buffer pH values. The values are usually given on the buffer label. Most technical buffers correspond to the values listed in the table shown here on the left. -
