Product Description
116L 4-Gas Calibration Gas – 18.5% Oxygen Deficiency Validation
This 116 Liter reactive 4-gas calibration cylinder is formulated to simulate pronounced oxygen-deficient conditions at 18.5% O₂, enabling technicians to validate alarm activation below OSHA’s 19.5% minimum safe limit.
Gas composition:
-
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 mixture creates a clearly measurable deficiency environment for confirming alarm setpoints while simultaneously verifying toxic and combustible detection channels.
With 1000 PSI fill pressure and 4.0 cubic feet of capacity, the 116L format supports recurring bump testing cycles and audit-driven compliance programs across multiple gas monitors.
