Product Description
CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 60L Cylinder
This precision calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.0%, balanced in nitrogen to simulate slightly reduced oxygen conditions while maintaining accurate multi-gas detector calibration. Supplied in a 60L aluminum cylinder at 1000 PSI with a C-10 valve, this mixture is ideal for calibration workflows that require validation beyond standard atmospheric conditions.
