Product Description
66L 4-Gas Calibration Gas – 18.0% Oxygen Deficiency Simulation
This 66 Liter reactive 4-gas calibration cylinder is engineered to simulate pronounced oxygen-deficient environments at 18.0% O₂, providing a deeper deficiency condition for alarm validation and safety training scenarios.
Gas mixture includes:
-
Hydrogen Sulfide (H₂S) – 10 PPM
-
Carbon Monoxide (CO) – 50 PPM
-
Methane (CH₄) – 2.5% (50% LEL)
-
Oxygen (O₂) – 18.0%
-
Nitrogen Balance
At 18.0% oxygen, this blend produces a clearly measurable low-O₂ environment, allowing safety professionals to confirm alarm activation and sensor performance under more aggressive deficiency conditions.
The 66L cylinder with 1150 PSI fill pressure provides balanced capacity for recurring confined space programs while maintaining manageable portability.
