    Product Description

    CO 100 PPM / CH₄ 2.5% (50% LEL) / O₂ 20.9% Calibration Gas – 103L Cylinder

    This calibration gas blend contains Carbon Monoxide (CO) 100 PPM, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 20.9%, balanced in nitrogen to replicate normal atmospheric conditions for accurate multi-gas detector calibration. Supplied in a 103L steel cylinder at 1000 PSI with a C-10 valve, this disposable configuration provides a strong balance between portability and extended operational use.
