Product Description
116L CO₂ (25%), CH₄ (50% LEL), and O₂ Calibration Gas – Flexible High-Range IR & LEL Testing
This 116L custom calibration gas cylinder is designed for facility calibration programs requiring elevated CO₂ concentration accuracy with flexible handling and standard combustible gas verification.
The mixture includes 25.0% Carbon Dioxide (CO₂) for high-range IR (NDIR) sensor calibration, 2.5% Methane (50% LEL) for standard combustible gas response testing, and 20.9% Oxygen (O₂) to simulate normal atmospheric conditions.
This blend is ideal for multi-gas detectors requiring consistent calibration across CO₂, methane, and oxygen sensors in operational environments.
