Product Description
19.0% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 66L Cylinder
This 19.0% oxygen calibration gas is designed to simulate oxygen-deficient environments, enabling accurate gas detector validation under real-world confined space and industrial conditions.
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 reliable early detection performance. Oxygen at 19.0% represents mild oxygen deficiency, making this gas ideal for validating detector response before conditions reach critical safety thresholds.
Supplied in a 66L aluminum cylinder at 1150 PSI with a C-10 valve, this configuration supports routine calibration in slightly hazardous environments, balancing portability with sufficient runtime for operational use.
