Ph values at different temperatures – Hanna Instruments HI 221 User Manual

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 corre-
sponding to the measured or set temperature.

pH VALUES AT DIFFERENT
TEMPERATURES
During calibration the instrument will display the buffer value at 25 °C.
