Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 11L Cylinder
This 20.9% oxygen calibration gas is designed for rapid calibration under normal atmospheric conditions, enabling immediate and reliable gas detector performance checks in the field.
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 accurate early detection. Oxygen at 20.9% replicates ambient air conditions, making this gas ideal for quick bump testing, compliance checks, and daily safety validation.
Supplied in an 11L aluminum cylinder at 140 PSI with a trigger valve, this disposable configuration provides controlled, on-demand gas release, allowing technicians to perform fast, efficient detector verification with minimal setup.
