Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 17.0% Calibration Gas – 680L Cylinder
This high-volume calibration gas blend contains Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 17.0%, balanced in nitrogen to simulate oxygen-deficient environments while maintaining accurate multi-gas detector calibration. Supplied in a 680L aluminum cylinder at 1800 PSI with a CGA-specific valve, this configuration is designed for large-scale calibration programs requiring extended usage and minimal cylinder changeover.
Cylinder & Mixture Details
