Product Description
116L 4-Gas Calibration Gas – 35 PPM CO Compliance Configuration
This 116L reactive 4-gas calibration cylinder is engineered for organizations validating 35 PPM carbon monoxide first-alarm setpoints within structured confined space and industrial hygiene programs.
The 18.0% oxygen concentration simulates an active oxygen-deficient atmosphere below OSHA’s 19.5% threshold, enabling comprehensive multi-sensor verification.
