Product Description
4-Gas Calibration Gas for Portable Multi-Gas Detector Verification
This 4-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 used for calibration and bump testing of portable multi-gas detectors that 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 calibration gas cylinder provides a dependable solution for routine detector maintenance and sensor 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 reflects normal atmospheric oxygen, allowing technicians to confirm oxygen sensor performance while verifying combustible and toxic gas detection.
