Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 34L 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. Packaged in a 34L steel cylinder at 500 PSI with a CGA-600 valve, this disposable configuration is ideal for portable use and efficient field calibration.
