pH BUFFER TEMPERATURE DEPENDENCE
Temperature has an effect on pH. The calibration buffer
solutions are affected by temperature changes to a lesser
degree than normal solutions.
For manual temperature calibration please refer to the following chart.
For instance, if the buffer temperature is 25°C, the display
should show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10
buffers, respectively.
At 20°C, the display should show pH 4.00, 7.03 or 10.06.
The meter reading at 50°C will then be 4.06, 6.98 or 9.82.
