Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 116L Cylinder
This 20.9% oxygen calibration gas is designed for routine calibration under normal atmospheric conditions, ensuring consistent gas detector performance in daily operations.
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, validating early detection thresholds. Oxygen at 20.9% replicates ambient air, making this gas ideal for compliance-driven calibration and maintenance workflows.
Supplied in a 116L aluminum cylinder at 1000 PSI with a C-10 valve, this configuration is optimized for spec-matched calibration programs, where exact cylinder size and pressure must be maintained without substitution.
