The QMA601 Process Moisture Analyzer provides highly reliable, fast and accurate measurement of moisture content in a wide variety of carrier gases. It has a lower detection limit of 0.1 ppmV with reliable accuracy at sub-ppm trace moisture levels. Using Michell's latest developments in Quartz Crystal Microbalance technology the analyzer measures moisture levels effectively even in gases with changing background compositions. Suitable for use with natural gas containing up to 20 % hydrogen with no further modification required.

The QMA601-LR Moisture Analyzer is designed to provide reliable, fast and accurate measurement of ultra-low trace moisture content in natural gas in NGL fractionation and LNG liquefaction applications. It has a lower detection limit of 0.02 ppmV with reliable accuracy at sub-ppm trace moisture levels. The low-range variant is the result of Michell Instruments' ongoing efforts to improve Quartz Crystal Microbalance technology for ultra-low trace moisture measurements down to 20ppbV.

The QMA601 Moisture in CO2 analyzer is the latest variant of the well-established Quartz Crystal Microbalance analyzer range from Michell Instruments. This analyzer is the result of some novel development work and offers an accurate, reliable and traceable measurement solution for CO2 capture, transportation and storage projects.

The next generation Advanced Quartz Crystal Microbalance analyzer from Michell Instruments is designed to provide reliable, fast and accurate measurement of trace moisture content in a variety of applications where keeping moisture to a minimum is of critical importance. The analyzer provides consistently accurate measurements of trace moisture. This consistency is achieved using a self-calibration system, which adjusts the sensor with reference to an internal moisture generator.

Promet EExd Process Moisture Analyzers are hazardous-area rated industrial hygrometer systems for measurement of water vapor content in process gases on natural gas platforms and terminals as well as in petrochemical plants and industrial manufacturing facilities. The Promet EExd is installed directly in the hazardous area, simplifying site installation and retrofits. Suitable for use with natural gas containing up to 20 % hydrogen with no further modification required.

Promet I.S. Process Moisture Analyzers are heavy duty, industrial hygrometer systems for measurement of high pressure, process gases and vaporized liquids on natural gas platforms and terminals, petrochemical plants and industrial gas manufacturing facilities. Promet I.S. combines Michell's proven Ceramic Metal-Oxide Moisture Sensor with ES70 sample conditioning systems to provide a reliable and easy to operate, multi-channel on-line instrument for both flammable and non-flammable gases.

This flexible multi-channel analyzer is designed to provide real-time, multi-parameter displays for our industrial hygrometer systems for measurement of high pressure, process gases and vaporized liquids on natural gas platforms and terminals, petrochemical plants and industrial gas manufacturing facilities. Optional oxygen electrochemical sensors offer additional capability for percentage and ppmV O2 measurements.

The ADG400 is a two-stage dew-point generator which operates in the range of -80...+20 °Cdp (-112...+68 °Fdp). It features a touchscreen HMI, which allows the user to set the desired dew point, or create and run an automated calibration profile. The generator can also be operated remotely and integrated into customer software via the USB interface.

The DCS system is a complete rack-mounted calibration station capable of producing a flow of air (or nitrogen) at a pre-specified range of dew-point temperatures from a minimum of -100°C (-148°F) to a maximum of +20°C (+68°F). Through customization the DCS system can be PC controlled for automated calibration sequences or manually operated at pre-determined dew-point set points.

The DG2 has two stages of gas-flow mixing which allow it to generate dew points down to -75°Cdp (-103°Fdp). The great strengths of the DG2 are its ease of use and its flexibility in manually generating an accurate target dew point by fine tuning the gas mix via its flow metering valves. Infinite mixing is achievable within its working range.

The DG3 is our entry-level, single-stage mixing humidity generator. It is operated by manually mixing the two gas streams using flow control valves. The DG3 provides flows up to 5 Nl/min (10.6 scfh) and generates dew points ranging from -40 to +20°Cdp (-40 to +68°Fdp).
