Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 34L Portable Cylinder for Field Calibration
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for portable multi-gas detector calibration under real atmospheric conditions, supporting accurate verification of toxic, combustible, and oxygen sensors.
With 1.05% LPG (50% LEL), this mixture ensures reliable calibration of combustible gas (LEL) sensors, while the 20.9% oxygen level replicates ambient air, allowing for real-world detector performance validation.
The 34 liter disposable cylinder provides extended use compared to smaller cylinders, while remaining compact enough for field deployment, making it ideal for technicians performing routine safety checks.
