Product Description
4-Gas Calibration Gas for Multi-Detector Calibration Programs
This quad gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 300 ppm, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0% balanced with Nitrogen.
The mixture is used for calibration and bump testing of portable multi-gas detectors that monitor toxic gases, combustible gases and oxygen levels in industrial work environments.
Supplied in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides extended calibration capacity for maintenance teams responsible for multiple gas detection instruments.
Gas Composition – Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Methane (CH₄) and Oxygen (O₂)
| Gas | Concentration |
|---|---|
| Hydrogen Sulfide (H₂S) | 10 ppm |
| Carbon Monoxide (CO) | 300 ppm |
| Methane (CH₄) | 1.45% (58% LEL Pentane Equivalent) |
| Oxygen (O₂) | 15.0% |
| Balance Gas | Nitrogen |
This H2S CO CH4 O2 calibration gas mixture is commonly used to verify detector response and maintain accurate monitoring of toxic gases, combustible gases and oxygen concentrations during industrial safety operations.
Cylinder Specifications

The 116L cylinder size provides a larger gas supply than field cylinders while remaining easier to manage than the largest calibration cylinders used in high-volume calibration environments.
Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space safety monitoring
• Industrial hygiene inspections
• Gas detector sensor verification
Routine calibration ensures detectors accurately respond to hydrogen sulfide exposure, elevated carbon monoxide levels, combustible gases and oxygen concentration changes.
