The Elcometer 130 Model S does not have automatic temperature compensation and therefore, the
actual level of soluble salts needs to be calculated manually using the following equation:
k =
Example: Measured Value: 12.3
k =
If using the Elcometer 130 Model T with Automatic Temperature Compensation disabled, the same
equation should be used to correct the gauge reading for temperature variances.
