Product Description
CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 66L Cylinder
This calibration gas mixture 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 66L aluminum cylinder at 1150 PSI with a C-10 valve, this blend is ideal for standard calibration environments where oxygen levels closely match ambient air.
