Product Description
CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.0% Calibration Gas – 116L Cylinder
This 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 controlled, slightly reduced oxygen environments. This allows for accurate multi-gas detector calibration when validating performance beyond standard atmospheric conditions. Supplied in a 116L aluminum cylinder at 1000 PSI with a C-10 valve, this configuration is ideal for structured calibration programs requiring consistent and repeatable results.
