About This Product

The QMA401 Quartz Crystal Moisture Analyzer uses a next-generation advanced quartz crystal to provide reliable, fast and accurate measurement of trace moisture content in applications where minimizing moisture in the process is critical. is designed to provide. This product provides consistent and accurate measurements of trace moisture in sampling lines. This "consistency" is achieved using a self-calibration system that calibrates the sensor relative to an internal moisture generator. The moisture generator remains traceable to NPL and NIST, ensuring long-term stability of measurements. Featuring an intuitive LCD touchscreen design, measurement and system information is always displayed on the screen, and trend data can be downloaded to a PC via Ethernet or Modbus for external analysis. You can.
