Product Description
120L 4-Gas Calibration Gas – 19.0% Oxygen Deficiency Simulation for Fleet Programs
This 120 Liter reactive 4-gas calibration cylinder is engineered for organizations requiring repeatable oxygen-deficiency simulation at 19.0% O₂, below OSHA’s 19.5% minimum threshold.
Gas mixture includes:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 19.0%
-
Nitrogen Balance
The 19.0% oxygen concentration creates a measurable low-oxygen condition to confirm alarm activation while simultaneously validating toxic and combustible sensor response during bump testing and scheduled calibration cycles.
With 1050 PSI fill pressure and 4.2 cubic feet of capacity, the 120L configuration reduces replacement frequency and supports structured weekly or monthly compliance programs across multiple detectors.
