Features
Applications
The reliable spot checking portable
Ideal for spot checks of dew point or moisture content, the MDM300 and MDM300 I.S. include all the features needed for efficient work. An extremely fast response and accurate, stable measurement are complemented by an instrument that is easy to use and has data-logging, and built-in sampling components as standard. The instrument can be supplied with a range of accessories including sampling systems and a professional carry case. For use in Hazardous Areas, the MDM300 I.S. is fully certified in accordance by ATEX, IECEx, UKCA, USA, Canadian & EAC Ex - TR CU 012 requirements. Refer to the specification section for full product approval codings. The MDM300 and MDM300 I.S. are both IP66/ NEMA 4 rated and therefore suitable for demanding outdoor applications.
Measurement range
The MDM300 series can provide measurement to -76°F (-60°C) dew point in gases at atmospheric pressure in less than 15 minutes (30 minutes to -76°F/-60°C dew point for MDM300 I.S.). Combined with no required waiting time between measurements, allows the user to take many readings per day, increasing efficiency and reducing costs when compared to other instruments on the market.
Ease of use
The rugged but ergonomic design of the MDM300 series combines industrial durability with comfortable one or twohanded operation. The intuitive menu system and large, easy-to-press buttons enable the user to easily configure the instrument to display the parameters they require, even with gloved hands.
Measurement performance
Best-in-class accuracy of 1.8°F (1°C) dew point -76 to 68°Fdp (-60 to 20°Cdp) gives the user improved measurements. Every instrument undergoes a 13-point calibration over a period of 10 days and all calibration certificates are traceable to national standards via the NPL (UK) and NIST (USA).
In addition, the MDM300 series can be used to check and recalibrate Michell Easidew dew-point transmitters, affording the user the benefit of verification without the associated downtime.
Sampling solutions
The MDM300 series offers versatile sampling arrangements ranging from simply fixed orifices for low-pressure measurement to configurable high-pressure sampling systems up to 350 barg (5076 psig). A number of application kits are available providing out-of-the-box sampling systems specifically for the most popular applications. Please contact Michell Instruments for further details.
Hazardous certifications
The MDM300 I.S. has been certified by ATEX and IECEx, cQPSus, and EAC for use in hazardous areas. This is the perfect portable instrument for use in natural gas plants, petrochemical refineries, offshore platforms, and a range of other hazardous areas.
Sensing technology
The MDM300 uses Michell's highly developed ceramic metal oxide moisture sensor, which is constructed using state-of-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-meter.
