Product Description
CO 50 ppm / Pentane 0.14% (10% LEL) / Oxygen 18.0% Calibration Gas – 66L Aluminum Cylinder
This calibration gas mixture is designed for precision calibration of gas detection systems at ultra-low combustible gas thresholds. Featuring Carbon Monoxide (CO) at 50 ppm, Pentane (C₅H₁₂) at 10% LEL, and slightly reduced Oxygen (O₂) at 18.0%, it enables accurate validation of detector sensitivity across toxic, combustible, and oxygen monitoring channels.
This blend is ideal for environments where early gas detection and low-level alarm accuracy are critical.
