Product Description
CO 50 ppm / Pentane 0.35% (25% LEL) / Oxygen 12.0% Calibration Gas – 120L Cylinder
This calibration gas mixture is designed for accurate calibration of gas detection systems in severely oxygen-deficient environments. Featuring Carbon Monoxide (CO) at 50 ppm, Pentane (C₅H₁₂) at 25% LEL, and reduced Oxygen (O₂) at 12.0%, it enables reliable validation of detector performance across toxic, combustible, and oxygen monitoring channels.
The 120L cylinder supports routine operational calibration programs, providing consistent gas output for scheduled testing without transitioning to high-capacity bulk systems.
