Product Description
4-Gas Calibration Gas for Routine Detector Calibration Programs
This quad gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 60 ppm, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0% balanced with Nitrogen.
The mixture is commonly used for calibration and bump testing of portable multi-gas detectors used in confined space monitoring, industrial safety programs and environmental hazard detection.
Supplied in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides an extended gas supply for routine detector verification and maintenance.
Gas Composition – Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Methane (CH₄) and Oxygen (O₂)
| Gas | Concentration |
|---|---|
| Hydrogen Sulfide (H₂S) | 10 ppm |
| Carbon Monoxide (CO) | 60 ppm |
| Methane (CH₄) | 1.45% (58% LEL Pentane Equivalent) |
| Oxygen (O₂) | 15.0% |
| Balance Gas | Nitrogen |
This H2S CO CH4 O2 calibration gas mixture is widely used to verify detector response and ensure reliable monitoring of toxic gases, combustible gases and oxygen levels before entering hazardous work environments.
