Product Description
High-Capacity Quad Gas Calibration Mixture for Multi-Gas Detector Programs
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 designed for calibration and bump testing of portable multi-gas detectors used in industrial safety monitoring, confined space entry programs and gas detection maintenance schedules.
Supplied in a 120L aluminum cylinder pressurized to 1050 PSI with a C-10 valve, this large-capacity calibration gas cylinder supports facilities maintaining multiple detectors or performing frequent calibration procedures.
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, enabling technicians to verify oxygen sensor performance alongside toxic gas and combustible gas sensor response.
