Michell Instruments humidity probe calibration solution

Michell Instruments has released a solution for in-house calibration of humidity probes. The benefits of performing calibrations in-house include less process downtime as well as reduced costs since fewer probes will be sent to external calibration laboratories. However, the capital outlay required for traditional systems is prohibitive for all but the largest companies. Michell has combined its HygroCal 100 humidity validator with the Optidew 401 chilled mirror hygrometer to place in-house calibrations in the reach of more companies.

Michell’s Optidew 401 chilled mirror hygrometer is traceable to national standards to provide a reference for humidity calibrations. It is accurate to ±0.15°C dew point and ±0.15°C temperature, and connects easily to the HygroCal 100. Both instruments are light and compact, allowing users to easily move the system to where it is needed most or to be packed away if not required.

The HygroCal 100 is a lightweight, portable humidity verifier, which uses its internal polymer reference to provide automatic verifications of the accuracy of RH probes. The HygroCal 100 interface enables users to assign a hygrometer with an analog output as a reference device. This allows the unit to be used to perform full calibrations of humidity probes, which are traceable to the reference used.

Michell has also partnered with fellow a process sensing technologies company, Rotronic, to provide commercial calibration services in ISO17025 accredited laboratories and fully functional dew-point calibration systems with climatic chambers, as well as transportable humidity generators for field calibrations.
