Best-in-class accuracy of 1°C dew point (-60...+20°C) gives the user improved measurements
Every instrument undergoes a 13-point calibration over a period of 10 days
All calibration certificates are traceable to NIST
Simple to install and maintain, the portable dew-point hygrometer has a sensor service exchange program which reduces the cost of maintenance. The MDM300 uses Michell’s highly developed ceramic metaloxide moisture sensor, which is constructed using stateof-the-art thin and thick film techniques.
Operation of the sensor depends upon the adsorption of water vapor into a porous non-conducting ‘sandwich’ between two conductive layers built on top of a base ceramic substrate. The active sensor layer is very thin – less than one micron and the porous upper layer that allows transmission of water vapor into the sensor is less than one nano-metre.
