Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 17.0% Calibration Gas – 66L Cylinder
This 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 lower oxygen environments for accurate multi-gas detector calibration. Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this mixture is designed for applications requiring more aggressive oxygen reduction than standard calibration atmospheres.
Cylinder & Mixture Details
