Product Description
66L 4-Gas Calibration Gas – 19.0% Oxygen Deficiency Simulation Blend
This 66 Liter reactive 4-gas calibration cylinder is formulated for controlled oxygen-deficiency simulation at 19.0% O₂, allowing technicians to verify alarm activation below OSHA’s 19.5% 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
At 19.0% oxygen, this blend creates a measurable deficiency condition to confirm proper low-oxygen alarm response while simultaneously validating toxic and combustible detection channels.
With 1150 PSI fill pressure and 2.3 cubic feet of capacity, the 66L configuration offers balanced portability for field validation and structured safety testing programs.
