Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 103L Cylinder for Extended Field Calibration
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for extended multi-gas detector calibration under ambient atmospheric conditions, ensuring accurate verification of toxic, combustible, and oxygen sensors.
With 1.05% LPG (50% LEL), this mixture provides precise calibration of combustible gas (LEL) sensors, while the 20.9% oxygen concentration replicates normal air conditions, delivering reliable real-world detector performance.
The 103 liter disposable cylinder offers a mid-range capacity solution, making it ideal for teams needing longer calibration cycles without transitioning to larger bulk cylinders.
