Product Description
60L 4-Gas Calibration Gas – 18.5% Oxygen Deficiency Verification
This 60 Liter reactive 4-gas calibration cylinder is engineered to simulate oxygen-deficient conditions at 18.5% O₂, enabling technicians to validate low-oxygen alarm activation under pronounced deficiency levels.
Gas composition includes:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 18.5%
-
Nitrogen Balance
At 18.5% oxygen, this blend creates a measurable deficiency condition below OSHA’s 19.5% minimum, allowing safety teams to confirm alarm performance while simultaneously validating toxic and combustible channels.
The 60L cylinder with 1000 PSI fill pressure supports recurring bump testing cycles across multiple detectors without excessive storage footprint.
