Product Description
Quad Gas Calibration Mixture for Portable Detector Calibration
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 100 ppm, Methane (CH₄) 1.25% (25% LEL), and Oxygen (O₂) 20.9% balanced with Nitrogen.
The mixture is used to calibrate and bump test portable multi-gas detectors used in industrial safety monitoring, confined space entry programs and routine gas detection equipment maintenance.
Supplied in a 60L aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this calibration gas cylinder provides 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) | 25 ppm |
| Carbon Monoxide (CO) | 100 ppm |
| Methane (CH₄) | 1.25% (25% LEL) |
| Oxygen (O₂) | 20.9% |
| Balance Gas | Nitrogen |
The 20.9% oxygen concentration represents atmospheric oxygen, allowing technicians to confirm oxygen sensor accuracy alongside combustible and toxic gas sensors.
Cylinder Specifications
| Specification | Value |
|---|---|
| Cylinder Size | 60L |
| Pressure | 1000 PSI |
| Cylinder Material | Aluminum |
| Valve Type | C-10 |

The 60L cylinder size is commonly used in portable calibration kits where technicians require a manageable cylinder that still supports repeated bump testing and detector verification.
Common 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 accurately respond to hydrogen sulfide exposure, carbon monoxide hazards, combustible methane levels and oxygen monitoring.
