Product Description
Large-Capacity Quad Gas Calibration Gas for Detector Maintenance
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 300 ppm, Methane (CH₄) 1.4% (28% LEL), and Oxygen (O₂) 18.0% 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 across industrial safety environments.
Supplied in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides an extended calibration gas supply for maintenance teams responsible for multiple gas monitoring 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) | 1.4% (28% LEL) |
| Oxygen (O₂) | 18.0% |
| Balance Gas | Nitrogen |
This H2S CO CH4 O2 calibration gas mixture allows technicians to verify proper detector response across toxic gas sensors, combustible gas sensors and oxygen monitoring sensors before hazardous work operations.
Cylinder Specifications

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