Product Description
CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 221L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 200 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.0%, balanced in nitrogen to replicate near-atmospheric conditions while maintaining accurate multi-gas detector calibration. Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this disposable configuration is designed for extended calibration cycles and simplified handling across larger operations.
