Product Description
60L 4-Gas Calibration Gas – 19.5% Oxygen for Deficiency Alarm Testing
This 60 Liter reactive 4-gas calibration cylinder is engineered for technicians who must verify oxygen-deficiency alarm activation at the OSHA threshold of 19.5% O₂.
Gas composition:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 19.5%
-
Nitrogen Balance
At 19.5% oxygen, this mixture allows precise validation of oxygen sensors while simultaneously testing toxic (H₂S, CO) and combustible (CH₄ LEL) channels in multi-gas detectors.
The 60L capacity paired with 1000 PSI fill pressure supports recurring bump testing programs without the bulk of higher-volume cylinders.
