Our Capabilities

Our reference is able to generate and measure moisture content from as low as -95ºC frost point to +68ºC dew point over a temperature range from -10ºC to +70ºC with an uncertainty of +0.1ºC to 1.0ºC frost/ dew point range.

Our permanent laboratory calibration is SAC Accredited and our CMC (Calibration and Measurement Capability, expressed as Uncertainty) is as follows:-

 A Summary of our Accredited Calibration Measurement Capability is:-
