Product Description
120L CO, CH₄ (20% LEL), and O₂ Calibration Gas – Facility Calibration Standard
This 120L calibration gas cylinder is built for routine facility calibration programs, offering increased capacity over smaller cylinders while remaining manageable for daily use.
The blend includes 1.0% Methane (20% LEL) for controlled combustible gas calibration and 20.9% Oxygen to replicate real atmospheric conditions. Combined with 50 PPM Carbon Monoxide (CO), this mixture supports accurate multi-gas detector calibration across toxic, combustible, and oxygen sensors.
