QMA2030

 Process Moisture Analyzer
A precision, fast-responding analyzer with automatic calibration for a wide range of applications from high purity industrial gases to catalyst bed protection.
The QMA2030 Process Moisture Analyzer is designed to provide a reliable, fast and accurate measurement of trace levels of moisture content (ppbV and ppmV) in a wide variety of industrial applications where the direct measurement of true concentration of water molecules is of concern. The applied quartz crystal microbalance technology can directly measure the volume concentration of water as an impurity in a process gas.
For self-verification and diagnostics the analyzer incorporates automatic calibration using an internal reference source. The intuitive touch screen control panel provides easy operation. In addition, live measurement data and system information is always on view and the analyzer also has a data logging facility that allows trend data to be downloaded to an external USB storage device for analysis. On-screen alarms can be set at user defined levels. Alarm contacts, and a 4-20mA analogue output are provided for connection to external monitoring.
