Product Description
4 Gas H2S CO CH4 O2 Calibration Gas – 66L Cylinder
This 4-gas calibration mixture is designed for verifying detector response in hazardous atmospheres where oxygen depletion and combustible risk occur simultaneously. The lower oxygen concentration allows technicians to confirm alarm activation and response accuracy during bump testing and safety program validation.
Gas Concentrations

What This Cylinder Tests
A single exposure confirms:
-
Toxic gas detection response (H₂S & CO)
-
Oxygen-deficiency alarm activation
-
Combustible gas detection (methane LEL)
Useful when validating alarm thresholds rather than just sensor presence.
Typical Applications
-
Confined space entry safety checks
-
Alarm threshold verification
-
Training simulations
-
Industrial safety inspections
-
Routine bump testing
