Product Description
4-Gas Calibration Mixture for Oxygen Deficiency Detector Testing
This quad gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 35 ppm, Methane (CH₄) 0.5% (10% LEL), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is formulated for calibration and functional testing of portable multi-gas detectors used to detect toxic gas exposure, combustible gas hazards, and oxygen deficiency conditions in industrial and confined space environments.
Supplied in a 60L aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this calibration gas provides a practical cylinder size for routine detector maintenance programs.
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) | 18.0% |
| Balance Gas | Nitrogen |
The 18.0% oxygen concentration simulates oxygen-deficient conditions, enabling technicians to confirm oxygen sensor response when oxygen levels fall below normal atmospheric levels.
Cylinder Specifications
| Specification | Value |
|---|---|
| Cylinder Size | 60L |

The 60L cylinder size provides a balance between portability and capacity, making it suitable for technicians performing regular calibration across multiple gas detection instruments.
Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space monitoring programs
• Oxygen deficiency sensor verification
• Industrial hygiene monitoring
Routine calibration ensures gas detectors respond correctly to hydrogen sulfide exposure, carbon monoxide hazards, combustible methane concentrations and reduced oxygen levels.
