Product Description
Portable Quad Gas Calibration Gas for Detector Calibration
This four-gas calibration mixture contains Hydrogen Sulfide (H₂S) 25 ppm, Carbon Monoxide (CO) 50 ppm, Methane (CH₄) 1.25% (25% LEL), and Oxygen (O₂) 18.0% balanced with Nitrogen.
The mixture is used for calibration and bump testing of portable multi-gas detectors that monitor toxic gas exposure, combustible gas concentrations and oxygen levels in industrial safety environments.
Supplied in a 60L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, this cylinder offers a portable and reliable calibration gas source for technicians performing routine detector verification.
