Product Description
Custom Quad Gas Calibration Cylinder for Portable Gas Detectors
This custom 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 100 ppm, Methane (CH₄) 1.25% (25% LEL), and Oxygen (O₂) 19.0% balanced with Nitrogen.
The mixture is used for bump testing and calibration of portable multi-gas detectors that monitor toxic gases, combustible gases and oxygen levels in hazardous work environments.
Supplied in a 44L aluminum cylinder pressurized to 750 PSI with a C-10 valve, this calibration gas cylinder provides a compact and reliable solution for routine detector verification.
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) | 19.0% |
| Balance Gas | Nitrogen |
The 19.0% oxygen concentration simulates a reduced-oxygen environment, enabling technicians to confirm detector response for oxygen deficiency conditions while verifying combustible and toxic gas sensors.

Typical Applications
• Portable gas detector calibration
• Multi-gas monitor bump testing
• Confined space monitoring
• Industrial hygiene programs
• Gas detector sensor verification
Routine calibration ensures detectors respond correctly to hydrogen sulfide exposure, carbon monoxide hazards, combustible methane concentrations and oxygen-deficient environments.
