Product Description
221L 4-Gas Calibration Gas for Confined Space and Multi-Gas Detection
This 221L calibration gas cylinder is designed for calibration of detectors measuring Carbon Monoxide (CO) 50 PPM, Carbon Dioxide (CO₂) 5.0%, Methane (CH₄) 2.5% (50% LEL), and Oxygen (O₂) 18.0% balanced in Nitrogen. The adjusted gas concentrations simulate real-world confined space conditions, supporting accurate response across all sensor channels.
