21.3.3 Temperature Compensation
The slope of a pH sensor (section 21.3.2) is affected by temperature. This
effect is compensated for either by using an Automatic Temperature
Compensation (ATC) sensor or by entering the sample temperature
manually. Figure 21-3 shows the slope of a pH sensor at various
temperatures.
