Product Description
CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 17.0% Calibration Gas – 221L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 17.0%, balanced in nitrogen to simulate critically low oxygen environments where deficiency becomes immediately dangerous. This enables accurate multi-gas detector calibration when validating performance in high-risk, safety-critical scenarios. Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this configuration is designed for extended calibration cycles, reducing changeout frequency while maintaining consistent validation in life-threatening conditions.
