Michell Instruments MDM300 High Speed Dew Point Hygrometer

Michell Instruments MDM300 High Speed Dew Point Hygrometer

Ideal for spot checks of dew point or moisture content, the MDM300 includes all the features needed for efficient work. An extremely fast response and accurate, stable measurement are complemented by an instrument which is easy to use, has data-logging and built in sampling components

The MDM300 can provide measurement to -60°C dew point in gases at atmospheric pressure in less than 15 minutes (30 minutes to -60°C dew point for MDM300 I.S.). This, combined with no required waiting time between measurements, allows the user to take many readings per day, increasing effi ciency and reducing costs when compared to other instruments on the market. Simple to use The rugged but ergonomic design of the MDM300 combines industrial durability with comfortable one- or two-handed operation. The intuitive menu system and large, easy-to-press buttons enable the user to easily confi gure the instrument to display the parameters they require even with gloved hands.

Best-in-class accuracy of 1°C/1.8°F dew point (from -60 to +20°C (-76 to -4°F) dew point) gives the user improved measurements. Every instrument undergoes a 13 point calibration over a period of 10 days and all calibration certifi cates are traceable to national standards via the NPL (UK) and NIST (USA).

External sensor connection via 4-20mA loop-powered input. External sensors for the measurement of dew point, pressure or temperature can easily be connected to the MDM300, and their readings displayed on the screen. These inputs can also be used to augment the measurement, such as by producing live pressure compensation. In addition the MDM300 can be used to check and recalibrate Michell Easidew dew-point transmitters, affording the user the benefi t of a verifi cation without the associated downtime.
