Product Description
66L 4 Gas Calibration Gas – Low Oxygen (19.0%) CO, CH₄, O₂
This 66L 4 gas calibration gas is specifically designed for low-oxygen environment simulation, featuring 19.0% Oxygen (O₂) alongside Carbon Monoxide (CO) and Methane (CH₄) balanced in nitrogen.
Unlike standard atmospheric blends (20.9% O₂), this mixture allows technicians to verify detector response under oxygen-deficient conditions, making it critical for confined space safety and compliance testing.
