Product Description
116L 4-Gas Calibration Gas – 200 PPM CO with 20.9% O₂
This 116L reactive 4-gas calibration cylinder is engineered to validate 200 PPM carbon monoxide alarm setpoints while maintaining standard atmospheric oxygen at 20.9% O₂.
Designed for operational programs requiring steady calibration intervals across multiple instruments.
Gas Composition
-
Hydrogen Sulfide (H₂S): 10 PPM
-
Carbon Monoxide (CO): 200 PPM
-
Methane (CH₄): 2.5% (50% LEL)
-
Oxygen (O₂): 20.9%
-
Nitrogen: Balance
The 200 PPM CO concentration verifies upper toxic alarm thresholds.
The 20.9% oxygen level ensures calibration under realistic ambient air conditions.
