Building upon the success of our quartz-crystal moisture measurement technology, the 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.

  • Compatible Gases: Inerts (He, Ar, Ne, Xe, Kr) O2, H2, N2. Contact AMETEK to confirm compatibility with other gases.
