Product Description
4-Gas Calibration Gas – H₂S, CO, CH₄, O₂ Detector Calibration Mix
This 4-gas calibration gas mixture is designed for accurate calibration and bump testing of portable multi-gas detectors used in industrial safety, confined space monitoring, and compliance programs.
The mixture contains Hydrogen Sulfide (H₂S) 25 PPM, Carbon Monoxide (CO) 50 PPM, Methane (CH₄) 1.62% (50% LEL LPG equivalent), and Oxygen (O₂) 18.0%, balanced with nitrogen in a 44L disposable aluminum cylinder.
This concentration profile is commonly used for standard calibration of multi-gas monitors used in oil & gas operations, wastewater treatment plants, industrial hygiene programs, fire departments, and safety inspection environments.
The 750 PSI C-10 aluminum cylinder provides a compact and portable calibration gas solution suitable for field technicians, safety managers, and industrial maintenance teams performing regular instrument verification.
