Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 680L High-Capacity Cylinder for Facility Calibration
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is engineered for high-volume, facility-wide calibration programs, delivering 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 concentration replicates normal atmospheric conditions, making it ideal for real-world detector accuracy and compliance.
The 680 liter cylinder provides maximum calibration capacity, reducing replacement frequency and supporting large-scale operations with multiple detectors across teams or job sites.
