Product Description
4-Gas Calibration Mixture for Multi-Gas Detector Verification
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) 20.9% balanced with Nitrogen.
The mixture is formulated for calibration and functional testing of portable multi-gas detectors used in industrial safety programs to monitor toxic gases, combustible gas hazards and oxygen deficiency.
Supplied in a 116L aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this calibration gas cylinder provides dependable performance for facilities conducting regular detector 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) | 20.9% |
| Balance Gas | Nitrogen |
The 20.9% oxygen concentration simulates ambient atmospheric oxygen, enabling technicians to confirm proper oxygen sensor response while verifying combustible gas and toxic gas detection.
