The Opti-Cal is a stand-alone professional calibrator for RH sensors providing humidity and temperature profiling with an in-built, traceable cooled mirror reference hygrometer. The Opti-Cal compliments Michell%u2019s existing humidity generation range and adds the key features of temperature control, traceable reference and fast response.
Opti-Cal offers the opportunity to provide local calibration of RH sensors, without the need to send them away to a traceable laboratory or contract on-site calibration services. Opti-Cal will provide calibrations that are directly traceable to International Standards over a wide relative humidity range, and at any set temperature from 10 to 50 ºC.
System accuracy of /- 0.2 ºC dew point and 0.1 ºC temperature, with a measurement uncertainty (achieved through UKAS calibration of the dew-point and manufacturer of temperature sensors) of around /- 0.2 ºC at k=2 means that an overall uncertainty to better than 2% of measured value is achievable.
