Product Description
4-Gas Calibration Mixture for Portable Gas Detector Calibration
This multi-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 100 ppm, Methane (CH₄) 1.25% (50% LEL Pentane Equivalent), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is commonly used for calibration and bump testing of portable gas detection instruments that monitor toxic gases, combustible gases and oxygen concentration in industrial environments.
Delivered in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides a dependable gas supply for scheduled detector calibration and maintenance.

The 116L cylinder offers a larger calibration gas supply than typical field cylinders, helping reduce replacement frequency during ongoing detector maintenance programs.
Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space monitoring
• Industrial safety compliance checks
• Gas detector sensor verification
Regular calibration ensures reliable detector response to hydrogen sulfide exposure, carbon monoxide hazards, combustible gas levels and oxygen concentration changes.
