Product Description
CO 200 PPM / CH₄ 2.5% (50% LEL) / O₂ 19.0% Calibration Gas – 34L Cylinder
This calibration gas blend contains Carbon Monoxide (CO) 200 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 19.0%, balanced in nitrogen to simulate slightly reduced oxygen environments while maintaining accurate multi-gas detector 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.
