The calibration laboratory of Michell Instruments is UKAS accredited for the measurement of humidity and dew point. Michell Instruments has been the pioneer in humidity and dewpoint calibrations opening the first humidity calibration lab in UK. Today it offers a calibration service for most moisture sensors and instrumentation, carried out against test equipment traceable to NPL (National Physical Laboratory, London, UK) and NIST (National Institute of Standards & Technology, Maryland, USA) through Michell’s ISO/IEC 17025 UKAS (United Kingdom Accreditation Service) accreditation.
Your internal quality process requirements generally determine whether a factory adjustment certificate suffices or whether an ISO 17025 (SCS/UKAS) certificate is needed. SCS or UKAS certificates are generally required in the pharmaceutical industry, the medical technology industry, research and development and the food industry. ISO 17025 certifications are performed with high precision reference hygrometers and for temperature calibration, an equally high precision temperature bath is used. The best possible SCS or UKAS calibration accuracy can only be achieved if all process parameters are controlled and checked at the highest level – SCS or UKAS certification is therefore only possible in one of our accredited laboratories.
A standard traceable adjustment certification can be carried out in one of our 12 calibration laboratories. Traceable ISO9001 calibration from -100 to +90°C (-148 to +194°F) dew point
Michell Instruments understands and endorses the need to conform to recognized standards for quality and calibration. Our calibration laboratory maintains full traceability to British (NPL) and American (NIST) Humidity Standards. Our scope may be viewed on the UKAS website
Our UKAS accreditation is commonly recognised elsewhere in the world as EAL, or NVLAP (National Voluntary Laboratory Accreditation Program) in the USA.
