PH VALUES AT VARIOUS TEMPERATURE
Temperature has an effect on pH. The calibration buffer solutions are
effected by temperature changes to a lesser degree than normal
solutions.
For manual temperature calibration (standard with HI 8519 or op-
tional with HI 8417, HI 8520 and HI 8521) 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.
