Product Description
120L 4-Gas Calibration Gas – 100 PPM CO with 20.9% Oxygen
This 120L reactive 4-gas calibration cylinder is designed to validate 100 PPM carbon monoxide alarm thresholds while maintaining normal atmospheric oxygen at 20.9% O₂.
The larger cylinder capacity supports organizations running multiple detectors or routine calibration schedules across entire safety programs.
