Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 66L Cylinder for Ambient Condition Calibration
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for multi-gas detector calibration under atmospheric oxygen conditions, providing accurate response verification for toxic, combustible, and oxygen sensors.
With 1.05% LPG (50% LEL), this blend ensures precise calibration of combustible gas (LEL) sensors, while the 20.9% oxygen level replicates normal ambient air, making it ideal for real-world calibration accuracy.
The 66 liter cylinder offers a balanced capacity solution, suitable for routine calibration programs, field use, and industrial safety compliance workflows.
