Model 5920 UHP Moisture Analyzer Series Download printable brochure.
Building upon the success of our quartz-crystal moisture measurement technology, AMETEK’s Model 5920 is an easy-to-use process moisture analyzer that offers a truly remarkable combination of performance features: multi-gas compatibility, exceptional accuracy, on-line verification, fast response speed, and wide
measurement range. The 5920 is ideal for critical moisture measurement applications including high purity gas production and semiconductor gases. Equipped with an on-line verification system, this analyzer is designed to rapidly build and maintain operator confidence in its analyses. The verification system allows you to challenge the analyzer’s sensor at will using a zero gas to check its baseline stability to confirm the sensor’s stability and
sensitivity to low ppbv moisture concentrations.
