Product Description
4-Gas Calibration Mixture for Multi-Gas 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 used for calibration and functional testing of portable multi-gas detectors designed to monitor toxic gases, combustible gas hazards and oxygen deficiency conditions in industrial environments.
Supplied in a 66L aluminum cylinder pressurized to 1150 PSI with a C-10 valve, this calibration gas provides dependable performance for routine detector verification and maintenance.
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 environments, allowing technicians to verify oxygen sensor response when oxygen levels fall below normal atmospheric conditions.
