Traceable humidity calibrations
Published: 23 June, 2016
MICHELL INSTRUMENTS says the HygroCal100 is a lightweight, portable humidity verifier, which uses its reliable internal polymer reference to provide automatic verifications of the accuracy of RH probes. However the HygroCal100 interface enables users to assign any hygrometer with an analogue output as a reference device – such as a chilled mirror hygrometer.
This allows the unit to be used to perform full calibrations of humidity probes, which are traceable to the reference used.
Michell says the ability to perform traceable humidity calibrations in-house gives users of large numbers of humidity probes more control over their processes and maintenance programme and the benefits of this include less process downtime as well as reduced costs since fewer probes will be sent to external calibration laboratories.

MICHELL INSTRUMENTS says its new HygroCal100 humidity verifier provides a practical option for companies that are not able to invest in a full humidity calibration laboratory to verify their humidity probes in-house.
The new HygroSmart HS3 advanced interchangeable relative humidity and temperature probe from MICHELL INSTRUMENTS is said to be 100% configurable to allow maximum flexibility to the user. This gives users the ability to alter their RH and temperature measurements to keep step with changes or developments in their process, with no extra costs.
MICHELL INSTRUMENTS reports it has launched an improved version of its interchangeable relative humidity sensor – the HygroSmart I7000XP – which can enable users to carry out maintenance on industrial relative humidity and temperature transmitters in as little as 30 seconds. Michell says the new unit has been developed by its research department and features the latest polymer capacitive technology to give an accuracy of 1%RH.
