Product Description
Quad Gas Calibration Cylinder for Portable Gas Detector Maintenance
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 35 ppm, Methane (CH₄) 0.5% (10% LEL), and Oxygen (O₂) 20.9% balanced with Nitrogen.
The mixture is used for calibration and bump testing of portable multi-gas detectors designed to monitor toxic gas exposure, combustible gas hazards and oxygen concentration levels in industrial environments.
Supplied in a 60L aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this calibration gas cylinder offers a practical balance between portability and calibration capacity for field technicians.
Gas Composition – Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Methane (CH₄) and Oxygen (O₂)
| Gas | Concentration |
|---|---|
| Hydrogen Sulfide (H₂S) | 10 ppm |
| Carbon Monoxide (CO) | 35 ppm |
| Methane (CH₄) | 0.5% (10% LEL) |
| Oxygen (O₂) | 20.9% |
| Balance Gas | Nitrogen |
The 20.9% oxygen concentration represents normal atmospheric oxygen, allowing technicians to verify oxygen sensor accuracy while confirming combustible gas and toxic gas sensor performance.

The 60L cylinder size is commonly used in portable calibration kits where technicians require a manageable cylinder that still supports multiple bump tests and detector verification procedures.
Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space safety monitoring
• Industrial hygiene compliance testing
• Gas detector sensor verification
Routine calibration ensures detectors respond accurately to hydrogen sulfide exposure, carbon monoxide hazards, combustible methane concentrations and oxygen level changes.
