Product Description
Compact 4-Gas Calibration Cylinder for Portable Detector Checks
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 routine calibration and bump testing of portable multi-gas detectors used to monitor toxic gas exposure, combustible gas hazards and oxygen concentration in industrial environments.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI with a C-10 valve, this calibration gas cylinder provides a lightweight and convenient option for field technicians performing detector verification.
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 mirrors atmospheric oxygen levels, allowing technicians to verify oxygen sensor accuracy while confirming combustible gas and toxic gas detection.
