New RH hand meter from Michell is a simple reference for the calibration and validation of humidity probes


Michell Instruments' new RH hand meter, the MDM25, is an ideal reference instrument for use with humidity generators when calibrating or validating RH probes.

Large users of RH probes - such as laboratories, pharmaceutical companies, semiconductor manufacturers - find that in-house calibration of probes is highly cost-effective when compared to sending out sensors to an external laboratory for calibration and/or adjustment. The MDM25 provides a useful secondary reference for use when performing calibrations with a humidity generator, such as Michell's S503, and is a cost-efficient alternative to a chilled mirror reference, such as the Optidew Vision.

The display orientation of the MDM25 can be inverted so it can be read easily when the fixed probe is inserted into the S503. With a wide range of probes the MDM25 can be used easily and comfortably in many situations.

The MDM25's highly stable polymer-based sensor responds rapidly to changes in humidity and is coupled with a thermistor for accurate temperature measurement. Other measurement parameters which can be derived from temperature and humidity are available on the handheld: absolute humidity, wet bulb temperature and dew point. 		MDM25
