Gaseous Fuels Dew Point Tester
Model:JF22634
Introduction
This instrument is based on a high-quality high-precision dew point sensor, with fast response speed and high sensitivity. Battery-powered, low-power portable design, easy to use and operate. It can measure trace moisture content in various inert gases, and is suitable for various occasions with strict control requirements for moisture content.
