Gastec Carbonyl Sulfide (COS) Gas Detector Tubes provide a convenient method for measuring carbonyl sulfide concentrations in air using a compatible Gastec gas sampling pump.

Designed for on-site gas detection, industrial hygiene, workplace air monitoring, occupational safety, and environmental testing, Gastec detector tubes provide a simple visual method for measuring specific gas concentrations without requiring electronic gas detection equipment.

Multiple measuring ranges are available to accommodate different carbonyl sulfide monitoring applications, including lower-level and higher-concentration PPM measurements.

Common Applications

Gastec Carbonyl Sulfide Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational exposure assessment, chemical manufacturing and processing, petroleum and petrochemical operations, refineries, sulfur-containing gas monitoring, laboratory environments, environmental monitoring, process monitoring, and workplace safety applications where carbonyl sulfide may be present.

Important

A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Each Carbonyl Sulfide Detector Tube option includes 5 detector tubes and 5 pretubes, providing 5 complete tests per box. Always select the appropriate detector tube and measuring range for your target gas and follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific tube being used.
