Product Description
Compact Quad Gas Calibration Gas for Portable Detector Bump Testing
This 4-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 designed for calibration and bump testing of portable multi-gas detectors used in confined space monitoring, industrial safety inspections and routine detector maintenance.
Supplied in a 34L disposable aluminum cylinder pressurized to 500 PSI with a C-10 valve, this cylinder provides a lightweight calibration solution ideal for quick detector verification and portable bump test kits.
