Product Description
120L CO, CH₄ (20% LEL), and O₂ (17%) Custom Mix Calibration Gas – Facility Standard for Oxygen Deficiency Calibration
This 120L custom calibration gas cylinder is built for routine facility calibration programs requiring controlled gas environments, including oxygen-deficiency simulation and precision detector validation.
The mixture includes 1.0% Methane (20% LEL) for controlled combustible gas calibration and 17.0% Oxygen (O₂) to simulate reduced oxygen conditions. With 25 PPM Carbon Monoxide (CO), this blend enables accurate multi-gas detector calibration across toxic, combustible, and oxygen sensors.
As a custom mix, this gas can be tailored to meet specific detector requirements, regulatory standards, or specialized operational environments.
