Meteorological organizations, standards laboratories, pharmaceutical manufacturing plants, and other businesses or institutions that operate many calibrated instruments or sensors must have an effective calibration system in place. It is usually more sensible to perform calibrations in-house, rather than managing the cost and downtime (or availability of replacement calibrated sensors) associated with sending equipment away to an external commercial calibration laboratory.

Michell Instruments has a long history in the field of humidity calibration, originating in the design and provision of the Transfer Standard Dew-point Hygrometer (TSDH) to provide traceability to NIST (National Institute of Standards and Technology) for European calibration laboratories. As the largest manufacturer of dew-point sensors in Europe, Michell Instruments has over 2000 sensors under calibration at any moment in time, in our own production facility in Ely, UK, in addition to local calibration centres in Netherlands, France, Italy, Germany, China, Japan and USA. The development and optimization of our own calibration systems has helped us to build a comprehensive portfolio of calibration products and solutions that enable our customers to perform their own on-site humidity calibrations.
