Product Description
120L 4-Gas Calibration Gas – High-Capacity Cylinder for Fleet Compliance Programs
This 120 Liter reactive 4-gas calibration cylinder is engineered for organizations operating multiple portable gas detectors across job sites, facilities, or industrial operations.
Gas mixture contains:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 20.9%
-
Nitrogen Balance
The 20.9% oxygen concentration supports atmospheric baseline validation while simultaneously verifying toxic and combustible sensor performance during bump tests and scheduled calibration intervals.
With 1050 PSI fill pressure and 120L capacity, this configuration minimizes replacement frequency and supports structured safety programs.
