Michell Instruments - Moisture and Humidity Measurement

Michell Instruments is the international leader in the field of moisture and humidity measurement solutions. With more than 30 years' experience, Michell designs and manufactures a wide range of transmitters, dew-point hygrometers and sampling systems capable of measuring trace moisture, water dew point and hydrocarbon dew point in a wide range of applications.

Michell process analysers

Michell's dark spot technology, which was developed in partnership with Shell, offers a world-class solution for the measurement of hydrocarbon dew point. The range of process analysers and sampling systems can combine this technology with the Michell ceramic moisture sensor to create a comprehensive range of instruments to measure both natural gas and moisture content in process gases and liquids.

Online moisture and dew point analysers

Michell Instruments offers the most comprehensive range of process dew point and moisture on-line analysers in the market.

The range of intrinsically safe instruments offer a field-mounted sampling system and transmitter in combination with a safe-area control unit. Flameproof and explosion proof certified systems are also available.

Hydrocarbon dew point analysers

The accurate and reliable measurement of the moisture content and hydrocarbon dew point in natural gas is critical for gas quality measurements in pipelines and numerous gas turbine applications. The Condumax II provides continuous on-line measurement of the hydrocarbon dew-point temperature of natural gas. Advantages of the Condumax II include:

• Fully automatic, reliable, on-line analysis
• Objective, repeatable measurement
• Fundamental cooled mirror principle
• Self-cleaning
• Optional water dew point

Moisture in process gas and liquid measurement

In the petrochemical industry the measurement of moisture content in a multitude of process gases and liquids is one of the most difficult and demanding tasks for process engineers. Michell's range of analysers can help to increase plant efficiency and safety by helping to monitor, maintain or avoid certain levels of moisture in gases and liquids.
