Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 34L Cylinder
This 20.9% oxygen calibration gas is designed for routine calibration under normal atmospheric conditions, supporting accurate and reliable gas detector performance 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 correctly at early detection thresholds. Oxygen at 20.9% replicates ambient air conditions, making this gas ideal for daily calibration, bump testing, and compliance checks.
Packaged in a 34L steel cylinder at 500 PSI with a CGA-600 valve, this disposable configuration is optimized for portable, on-site use, allowing technicians to perform fast validation before and during normal operations.
