 The Quartz Crystal Microbalance (QCM) technology for moisture measurement is based on monitoring the frequency modulation of a hygroscopic-coated quartz crystal with specific sensitivity to water vapour. Bulk adsorption of water vapour onto the coated crystal causes an increase in effective mass, which reduces the resonant frequency of the crystal, in direct proportion to the water vapour pressure. This sorption process is fully reversible with no long-term drift effect, giving a highly reliable and repeatable measurement.
The QMA2030 Process Moisture Analyzer is designed to provide highly reliable, fast and accurate measurement of moisture content (ppbV and ppmV) in a wide variety of industrial pure gases. Utilising quartz crystal microbalance technology, the analyzer incorporates automatic calibration using an internal wet reference source and, with its intuitive touch screen control panel, provides easy operation. |
