Product Description
CO / LPG (50% LEL) / O₂ Calibration Gas – 120L Cylinder for Standard Calibration Programs
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is engineered for routine calibration of multi-gas detectors, delivering accurate response across toxic, combustible, and oxygen-deficient conditions.
With 1.1% LPG representing 50% LEL, this mixture is optimized for combustible gas (LEL) sensor calibration, ensuring proper detector response in flammable environments and confined spaces.
The 120 liter cylinder is a standard industry size, offering an ideal balance of capacity and handling for ongoing calibration programs.
