Product Description
Portable Quad Gas Calibration Gas for Multi-Gas Detector Testing
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 100 ppm, Methane (CH₄) 1.25% (50% LEL Pentane Equivalent), 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 gas exposure, combustible gas levels and oxygen concentration in industrial safety environments.
Supplied in a 60L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder provides a portable calibration gas solution for technicians performing routine detector maintenance and field verification.
