Product Description
Lightweight 4-Gas Calibration Gas for Portable Detector Calibration
This quad gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 60 ppm, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0% balanced with Nitrogen.
The mixture is designed for calibration and functional testing of portable multi-gas detectors used to monitor toxic gases, combustible gases and oxygen levels in industrial work environments.
Supplied in a 44L disposable aluminum cylinder pressurized to 750 PSI with a C-10 valve, the cylinder provides a compact and portable calibration source for technicians performing detector maintenance in the field.
