Product Description
66L 4 Gas Calibration Gas – 32% LEL Methane, CO, O₂ (Low-Range Precision Calibration)
This 66L 4 gas calibration gas is designed for precision multi-gas detector calibration, featuring 50 PPM Carbon Monoxide (CO), 1.62% Methane (32% LEL), and 19.0% Oxygen (O₂) balanced in nitrogen.
This formulation enables lower-threshold LEL validation, making it ideal for multi-point calibration programs where detector response must be verified across a broader range of gas concentrations.
