Product Description
Quad Gas Calibration Gas for Portable Multi-Gas Detectors
This 4-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 66L disposable aluminum cylinder pressurized to 1150 PSI with a C-10 valve, the cylinder provides a portable calibration solution for technicians performing routine detector verification and maintenance.
