    Product Description

    CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 120L Standard Cylinder for Industrial Calibration

    This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is engineered for routine 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 normal ambient air, delivering real-world detector performance validation.

    The 120 liter cylinder is a standard industry size, offering an ideal balance of capacity and handling for safety managers, technicians, and industrial environments.
