GMA Process Micro Water Analyzer

Grand's GMA is a robust on-line instrument that can be customized to meet users' specific application and technical requirements. This instrument features an extremely wide measurement range of -100~20 °C dew point, an accuracy of ±1 °C dew point, and a maximum pipeline pressure resistance of 40MPa. It provides real-time dual-line display, showing moisture content/dew point/pressure value/temperature value respectively. Additionally, it offers configurable alarm, analog output, and digital communication functions. It can be easily installed with intrinsic safety sensors in hazardous or safe areas to minimize sample transportation time, thereby ensuring a rapid response to changes in process moisture.

The GMA analyzer is equipped with a unique temperature and pressure measurement and compensation mode, while the Easidew PRO I.S humidity sensor adopts patented thick-film technology. The reliable and durable design of both ensures long-term accurate measurement of moisture in gas and liquid media.

The GMA Trace Moisture Analyzer is used to measure the moisture content and dew point in gases and non-polar liquids. It is installed on-line in an explosion-proof type and connected to the Easidew PRO I.S series moisture probes.
