Product Description
Compact Quad Gas Calibration Gas for Portable Detector Calibration
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 gases, combustible gases and oxygen concentration in industrial environments.
Supplied in a 44L disposable aluminum cylinder pressurized to 750 PSI with a C-10 valve, this cylinder provides a lightweight and portable calibration gas source for technicians performing field detector verification.
