Product Description
44L 4-Gas Calibration Gas – 19.0% Oxygen Deficiency Alarm Validation
This 44 Liter reactive 4-gas calibration cylinder is designed for technicians who need controlled oxygen-deficiency simulation at 19.0% O₂, below OSHA’s 19.5% minimum safe level.
Gas composition includes:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 19.0%
-
Nitrogen Balance
The reduced oxygen concentration allows verification that low-O₂ alarms trigger properly, while simultaneously validating toxic and combustible sensor channels in multi-gas monitors.
With 750 PSI fill pressure and 1.5 cubic feet of volume, the 44L cylinder provides practical portability for contractor use and smaller calibration programs.
