Product Description
Custom 4-Gas Calibration Mixture for Portable Detector Calibration
This custom quad 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 designed for calibration and bump testing of portable multi-gas detectors used to monitor toxic gases, combustible gas hazards and oxygen concentration levels in industrial safety environments.
Supplied in a 66L aluminum cylinder pressurized to 1150 PSI with a C-10 valve, this cylinder provides a reliable calibration gas source for detector maintenance and safety compliance testing.
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 represents a reduced oxygen environment, which can be used to verify detector response for oxygen-deficient conditions alongside combustible and toxic gas sensors.
