The MM400 moisture / dew point hygrometers are designed to be customised to your application giving precise measurements while providing a simple, yet affordable moisture analyzer.
Incorporating our high quality aluminium oxide moisture sensor which provides accurate, dependable results over a wide range from -100°C to +20°C (-148°F to 68°F) dew point. The aluminium oxide sensor is maintenance-free and is the popular choice for the most demanding applications. The MM400 moisture analyzer is available in three different configurations:
Panel-mounted bench mounted moisture analyzers
NEMA 4X / IP66 waterproof and weatherproof moisture analysis units
19 in. rack mount. Combine the moisture analyzer with any of our oxygen analyzers to create a dual gas analyser.
These units are completely configurable and include the ability to remote mount sensors and offer user-selectable units of Dew Point (°C or °F) or ppmv. Two versions of the sensor are available to meet your needs:
The general purpose sensor includes flow valves and can be mounted up to 1km from the analyser.
The intrinsically safe remote sensor allows for installations into hazardous areas. This sensor is approved by BASEEFA and CENELEC to ATEX II 1G/EEx ia IIC T4 standards.
Stainless steel housings, laboratory grade components and controlled environment manufacturing ensure the finest, most consistently precise sensors in the industry.
