Common Applications
Gastec Water Vapor Detector Tubes can be used with compatible Gastec sampling equipment for dew point testing, compressed air and gas systems, natural gas applications, pipeline and gas distribution systems, industrial gas monitoring, manufacturing processes, moisture measurement, quality control, laboratory testing, process monitoring, and industrial maintenance applications where water vapor or moisture concentrations need to be measured.
Important
A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Because the available Water Vapor Detector Tubes provide different measuring ranges and units, always select the appropriate part number based on the expected moisture concentration and your specific application.
Follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific detector tube being used.
