The temperature has an effect on pH. The calibration buffer solutions are

affected by temperature changes to a lesser degree than normal solutions.

During calibration the instrument will automatically calibrate to the pH value

corresponding to the measured or set temperature.

During calibration the instrument will display the pH buffer value at 25 ºC.
