Product Description
Compact Quad Gas Calibration Cylinder for Portable Gas Detectors
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 used for bump testing and calibration of portable multi-gas detectors designed to monitor toxic gases, combustible gases and oxygen levels in hazardous work environments.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI with a C-10 valve, this cylinder provides a lightweight calibration solution for technicians performing routine gas detector verification.
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 reflects normal atmospheric oxygen, allowing technicians to verify oxygen sensor performance alongside combustible gas and toxic gas detection sensors.
