Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 17L Cylinder
This 20.9% oxygen calibration gas is designed for routine calibration under normal atmospheric conditions, supporting fast and reliable gas detector performance checks in everyday 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, ensuring detectors respond accurately at early detection thresholds. Oxygen at 20.9% replicates ambient air conditions, making this gas ideal for quick bump tests, daily calibration, and compliance verification.
Packaged in a 17L steel cylinder at 240 PSI with a CGA-600 valve, this disposable configuration is optimized for rapid, on-site use, allowing technicians to perform immediate validation before equipment use.
