Product Description
CO / LPG (50% LEL) / O₂ (20.9%) Calibration Gas – 60L Cylinder for Standard Field Calibration
This Carbon Monoxide (CO), LPG (Propane), and Oxygen (O₂) calibration gas mixture is designed for accurate multi-gas detector calibration under ambient atmospheric conditions, supporting toxic gas, combustible gas, and oxygen sensor verification.
With 1.05% LPG (50% LEL), this blend ensures precise calibration of combustible gas (LEL) sensors, while the 20.9% oxygen concentration replicates normal air conditions, making it ideal for real-world detector performance validation.
The 60 liter cylinder is one of the most commonly used sizes, offering a practical balance of portability and calibration capacity for field technicians and industrial safety teams.
