CALCULATING TEMPERATURE COEFFICIENTS

To determine the temperature coefficient of your sample solution use this formula:
Where:
= Temperature coefficient

c
= Conductivity at Temp 1

= Temp 1

NOTE: A controlled temperature water bath is ideal for this procedure.
1. Immerse the probe into a sample of your solution and adjust the temperature
coefficient to 0% (that is, no compensation) by following instructions as described
in Section 6.5 – Temperature Coefficient.
2. Wait for 5 minutes. Note T
3. Condition the sample solution and probe to a temperature (T
10 °C different from T
NOTE: Record your results for future reference. Ideally T
measurement temperature, and should not differ by more than 5 °C.
4. Calculate the temperature coefficient of your solution according to the formula
shown above.
5. Enter the calculated temperature coefficient into the meter.
See Section 5.5 – Temperature Coefficient.
The calculated temperature coefficient will now be applied to all the meter readings.
