Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 116L Cylinder for Standard Calibration Programs
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for routine multi-gas detector calibration under ambient atmospheric conditions, supporting accurate performance of toxic, combustible, and oxygen sensors.
With 1.05% LPG (50% LEL), this blend delivers precise calibration of combustible gas (LEL) sensors, while the 20.9% oxygen level replicates normal air conditions, ensuring real-world detection accuracy.
The 116 liter cylinder offers a slightly lower pressure (1000 PSI) alternative to standard 120L cylinders, making it a strong option for buyers needing compatible specs while maintaining similar capacity.
