Product Description
CO / LPG (50% LEL) / O₂ Calibration Gas – 116L Cylinder for Flexible Calibration Programs
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for accurate calibration of multi-gas detectors, covering toxic exposure, combustible gas detection, and oxygen monitoring.
With 1.1% LPG (50% LEL), this blend ensures precise calibration of combustible gas (LEL) sensors, critical for detecting flammable hazards in confined spaces and industrial environments.
The 116 liter cylinder offers a slightly more compact alternative to standard 120L cylinders, making it ideal for teams that need efficient handling with minimal sacrifice in calibration capacity.
