Product Description
Portable 4-Gas Calibration Gas for Multi-Gas Detector Calibration
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 environments.
Supplied in a 60L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides a convenient calibration gas source for technicians performing routine detector verification and maintenance.
