Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 116L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 250 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0%, balanced in nitrogen to simulate reduced oxygen environments while maintaining accurate combustible and toxic gas calibration. Supplied in a 116L aluminum cylinder at 1000 PSI with a C-10 valve, this mixture is ideal for consistent detector performance in controlled atmospheric conditions.
