Product Description
CO 250 PPM / CH₄ 2.5% (50% LEL) / O₂ 18.0% Calibration Gas – 221L Cylinder
This calibration gas mixture features 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 multi-gas detector calibration. Packaged in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this disposable configuration is optimized for extended use and simplified handling.
