Product Description
11L CO₂ (3%), CH₄ (50% LEL), and O₂ (18%) Calibration Gas – Trigger Valve, No Regulator Required
This 11L custom calibration gas cylinder with trigger valve is designed for instant-use field calibration, eliminating the need for a regulator while supporting confined space simulation and multi-gas detector verification.
The mixture includes 3.0% Carbon Dioxide (CO₂) for IR (NDIR) sensor calibration, 2.5% Methane (CH₄) (50% LEL) for standard combustible gas testing, and 18.0% Oxygen (O₂) to simulate mildly reduced oxygen environments.
This blend is ideal for technicians who need fast, portable calibration without additional equipment in confined space environments.
