Product Description
11L CO₂ (25%), CH₄ (50% LEL), and O₂ 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 high-range CO₂, combustible gas, and oxygen sensor 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 technicians who need fast, portable calibration without additional equipment in the field.
