Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 17.0% Calibration Gas – 116L 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 oxygen-deficient environments while maintaining accurate multi-gas detector calibration. Supplied in a 116L aluminum cylinder at 1000 PSI with a C-10 valve, this mixture is ideal for routine calibration in controlled, reduced oxygen conditions.
