Product Description
High-Capacity 4-Gas Calibration Gas for Multi-Detector Maintenance
This quad gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 300 ppm, Methane (CH₄) 1.4% (28% LEL), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is designed for calibration and bump testing of portable multi-gas detectors used to monitor toxic gases, combustible gases and oxygen levels in industrial safety environments.
Supplied in a 120L disposable aluminum cylinder pressurized to 1050 PSI with a C-10 valve, this cylinder provides extended calibration capacity for facilities performing frequent gas detector maintenance.
Gas Composition – Hydrogen Sulfide (H₂S), Carbon Monoxide (CO), Methane (CH₄) and Oxygen (O₂)
