Product Description
Lightweight Quad Gas Calibration Gas for Portable Detector Testing
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 used for calibration and bump testing of portable multi-gas detectors used in industrial safety monitoring, confined space detection and routine instrument maintenance.
Supplied in a 44L disposable aluminum cylinder pressurized to 750 PSI with a C-10 valve, this compact cylinder provides a portable calibration gas source for technicians performing field detector verification.
