Product Description
221L CO, CH₄, and O₂ Calibration Gas for Multi-Gas Detectors
This high-capacity 221L calibration gas cylinder is designed for operations that require frequent calibration and minimal downtime. Featuring a precise blend of Carbon Monoxide (CO), Methane (CH₄), and Oxygen (O₂), this mixture supports accurate calibration and bump testing across a wide range of gas detection equipment.
With 1.62% Methane (50% LEL LPG equivalent), this gas provides dependable combustible gas simulation, while 50 PPM CO and 17.0% O₂ ensure proper response calibration for toxic and oxygen sensors.
