Product Description
680L CO, CH₄ (20% LEL), and O₂ Calibration Gas – High-Volume Calibration Supply
This 680L high-capacity calibration gas cylinder is engineered for large-scale calibration programs and high-throughput operations, where minimizing downtime and reducing cylinder changeouts is critical.
Featuring 1.0% Methane (20% LEL) and 20.9% Oxygen, this mixture is optimized for controlled, precision calibration environments, allowing accurate detector response testing without overexposure to higher LEL concentrations.
With 50 PPM Carbon Monoxide (CO) included, this blend supports full multi-gas detector calibration across toxic, combustible, and oxygen sensors.
