Product Description
19.0% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 221L Cylinder
This 19.0% oxygen calibration gas is engineered to simulate oxygen-deficient environments, enabling accurate and consistent gas detector validation in real-world confined space and industrial conditions.
The mixture includes Carbon Monoxide (CO) 100 PPM for toxic gas calibration and Methane (CH₄) 1.0% (20% LEL) for low-level combustible gas response verification, ensuring detectors respond reliably as hazardous conditions begin to develop. Oxygen at 19.0% represents early-stage oxygen deficiency, allowing calibration before conditions reach critical safety thresholds.
Supplied in a 221L steel cylinder at 250 PSI with a CGA-165 valve, this configuration is designed for extended calibration cycles, reducing the need for frequent cylinder changes while supporting consistent detector validation across ongoing operations.
