Product Description
60L 4-Gas Calibration Gas – LPG Equivalent LEL with 18.0% Oxygen
This 60L reactive 4-gas calibration cylinder is engineered for confined space gas detector calibration where both combustible gas response and oxygen-deficiency alarm thresholds must be verified.
The mixture includes 25 PPM hydrogen sulfide, 50 PPM carbon monoxide, 1.62% methane representing 50% LEL propane equivalent, and 18.0% oxygen, providing realistic atmospheric simulation for multi-sensor gas detection instruments.
Gas Composition
-
Hydrogen Sulfide (H₂S): 25 PPM
-
Carbon Monoxide (CO): 50 PPM
-
Methane (CH₄): 1.62% (50% LEL LPG / Propane Equivalent)
-
Oxygen (O₂): 18.0%
-
Nitrogen: Balance
The 18.0% oxygen concentration enables calibration of deeper oxygen-deficiency alarms used in confined space monitoring programs.
