DEPENDENCE

Temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a

lower 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.
