Product Description
CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9% Calibration Gas – 680L Cylinder
This high-volume calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.9%, balanced in nitrogen to replicate normal atmospheric conditions for accurate multi-gas detector calibration. Supplied in a 680L aluminum cylinder at 1800 PSI with a CGA-specific valve, this configuration is ideal for large-scale calibration programs requiring extended use and minimal cylinder changeout.
