Product Description
19.0% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 11L Cylinder
This 19.0% oxygen calibration gas is engineered to simulate oxygen-deficient environments, enabling immediate validation of gas detector performance before entering confined or hazardous spaces.
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 as hazardous conditions begin to develop. Oxygen at 19.0% represents early-stage oxygen deficiency, making this gas ideal for real-world pre-entry validation.
Supplied in an 11L aluminum cylinder at 140 PSI with a trigger valve, this disposable configuration allows for precise, instant gas release, enabling technicians to perform fast, controlled bump testing with minimal setup.
