Michell Instruments Ltd. - PRODUCT NEWS

Michell Instruments accredited by UKAS for relative humidity calibrations.

Michell Instruments Ltd has been awarded accreditation by UKAS (United Kingdom Accreditation Service) to perform calibrations on relative humidity instruments at their laboratory in Cambridge.

This indicates the highest level of confidence, from the UK's national accreditation service, in a laboratory's ability to perform calibrations in a controlled and repeatable manner.

The accreditation covers the relative humidity range 10 to 98% rh at temperatures from 10 to 82 Deg C and 10 to 73% rh from 82 to 90 Deg C. Uncertainty is 2% of measured relative humidity at temperatures from 0 to 90 Deg C and 2.3% of measured relative humidity from 10 to 20 Deg C (at a coverage factor of k=2). Best measurement uncertainty for temperature is +/- 0.2 Deg C.

Michell Instruments’ laboratory was the first to be UKAS accredited for the calibration of dew point hygrometers in1986. The laboratory has the widest dew point range of any hygrometer manufacturer, anywhere in the World, and is now accredited at humidity levels from –90 up to +82 Deg C dew point, with best uncertainty of 0.15 ºC dew point at k=2 (for +20 ºC dew point).

These latest extensions mean that Michell can offer a full range service for dew point and relative humidity calibration, at a competitive price, backed up by eighteen years’ experience in meeting and exceeding the exacting requirements of the UKAS accreditation system. The system has worldwide recognition through the EA, ILAC and IAF.

This places Michell at the forefront of the provision of humidity calibration instrumentation and services, both for relative and absolute humidity (dew point).
