Product Description
120L 4-Gas Calibration Gas – 35 PPM CO Enterprise Configuration
This 120L reactive 4-gas calibration cylinder is engineered for organizations operating lower CO first-alarm thresholds at 35 PPM, supporting early-warning carbon monoxide validation across large detector fleets.
The 18.0% oxygen concentration creates a controlled oxygen-deficient environment below OSHA’s 19.5% threshold, allowing comprehensive multi-sensor verification.
