Product Description
20.9% Oxygen Calibration Gas – CO 100 PPM / CH₄ 1.0% (20% LEL) – 103L Cylinder
This 20.9% oxygen calibration gas is designed for routine calibration under normal atmospheric conditions, delivering reliable and repeatable gas detector performance across 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, ensuring accurate early detection. Oxygen at 20.9% replicates ambient air conditions, making this gas ideal for compliance-driven calibration and maintenance workflows.
Supplied in a 103L steel cylinder at 1000 PSI with a C-10 valve, this configuration provides a balanced solution between portability and runtime, allowing teams to maintain efficient calibration without moving to larger, heavier cylinders.
