Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Testing
This quad 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 engineered for calibration and bump testing of portable gas detection instruments used to monitor toxic gas exposure, combustible gas hazards, and oxygen concentration levels.
Delivered in a 66 liter aluminum cylinder pressurized to 1150 PSI with a C-10 valve, this calibration gas cylinder provides a reliable solution for routine detector maintenance and safety compliance programs.
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 levels, allowing technicians to verify proper oxygen sensor response along with toxic and combustible gas sensors.
