The 1.62% Methane (50% LEL Propane Equivalent), 50 PPM Carbon Monoxide, 25 PPM Hydrogen Sulfide, and 18% Oxygen Calibration Gas Mixture is designed for the calibration, bump testing, and verification of compatible multi-gas detection and monitoring instruments.

This four-component calibration gas provides known concentrations of methane, carbon monoxide (CO), hydrogen sulfide (H₂S), and oxygen (O₂), balanced with nitrogen. The methane concentration is specified as 50% LEL propane equivalent, making this quad-mix suitable for compatible multi-gas detectors equipped with combustible gas, carbon monoxide, hydrogen sulfide, and oxygen sensors.
