Common Applications
Gastec Phosphine Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational exposure assessment, fumigation operations, grain and commodity storage facilities, agricultural applications, shipping and cargo operations, semiconductor manufacturing, chemical processing, laboratory environments, environmental monitoring, process monitoring, and workplace safety applications where phosphine may be present.
Important
A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Because several phosphine detector tube options are available with significantly different measuring ranges, always select the appropriate part number based on the anticipated phosphine concentration and your specific sampling application.
Follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific detector tube being used.
