Gastec Oxygen (O₂) Gas Detector Tubes provide a convenient method for measuring oxygen 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 oxygen concentrations without requiring electronic gas detection equipment.
Gastec Oxygen Detector Tubes provide a measuring range of 3–24% for applications requiring quick, on-site measurement of oxygen concentrations.
Gastec Oxygen Detector Tube Options:
Gastec 31B Oxygen Detector Tubes:
- Part Number: 31B
- Target Gas: Oxygen (O₂)
- Oxygen Measuring Range: 3–24%
- Tests: 5 tests per box
Common Applications
Gastec Oxygen Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational safety assessments, confined space evaluation, process monitoring, manufacturing facilities, laboratories, storage areas, environmental testing, and workplace safety applications where oxygen concentration measurements are required.
Important
A compatible Gastec Gas Sampling Pump is required to use these detector tubes. 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.
