Product Description
680L CO (50 PPM), CH₄ (50% LEL), and O₂ (16%) Calibration Gas – Toxic, LEL & Oxygen Deficiency Testing
This 680L custom calibration gas cylinder is designed for high-volume calibration programs requiring toxic gas detection, combustible gas verification, and oxygen-deficiency simulation.
The mixture includes 50 PPM Carbon Monoxide (CO) for toxic gas sensor calibration, 2.5% Methane (50% LEL) for standard combustible gas testing, and 16.0% Oxygen (O₂) to simulate mildly oxygen-deficient environments.
This blend is ideal for confined space monitoring, industrial safety compliance, and multi-gas detector calibration across large operations.
