Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 680L Cylinder
This 20.9% oxygen calibration gas is designed for standard atmospheric calibration at scale, ensuring reliable gas detector performance across large operations and continuous-use environments.
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, supporting accurate validation of early detection thresholds. Oxygen at 20.9% replicates ambient air conditions, making this gas ideal for routine calibration, bump testing, and regulatory compliance.
Supplied in a 680 liter aluminum cylinder at 1800 PSI with a CGA-specific valve, this configuration is engineered for high-volume calibration programs, reducing cylinder changeout frequency while supporting multiple detectors and teams simultaneously.
