PMA2030 analyser measures moisture in gases

Michell Instruments has introduced the PMA2030, which uses the quartz-crystal microbalance technique for moisture measurement in gases.

The PMA2030 quartz crystal analyser is an ideal quality-monitoring tool for air separators, industrial and high-purity gas production processes.

The analyser provides reliable, fast and accurate measurement at trace moisture levels (ppbv and ppmv).

The quartz crystal sensor of the PMA2030 will give a 63 per cent response to a step change in moisture in less than two minutes (95 per cent in less than five minutes).

The wide operating range - from 0.1 to 2000ppmV - coupled with the fast response of the PMA2030 helps to monitor and protect processes to avoid damage to tools or finished products by enabling users to react quickly to fluctuations in moisture.

The new analyser provides measurements that can be trusted throughout its operational life.

Michell's advanced quartz crystal technology gives a reproducible and linear response to changes in moisture content.

This allows the PMA2030 to deliver accuracy of five per cent of measured value in the range 0.5 to 500ppmV.

Its automatic calibration system, using an internal reference source, guarantees the sensor's integrity and accuracy by cancelling out the effects of contamination.

The PMA2030 is also easy to use as its touch-screen panel provides a user-friendly and intuitive interface.

The live measurement data and graph of the session are always on view and can be downloaded to a conventional external USB storage device for traceability or analysis.

The PMA2030 analyser enhances the range of moisture sensing technologies currently available from Michell.

Along with the metal oxide ceramic sensor, chilled mirror and capacitive technologies, the quartz crystal microbalance enables the customer to benefit from flexibility of choice between these complementary humidity-measurement technologies.
