Product Description
Quad Gas Calibration Gas for Portable Multi-Gas Detector Verification
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 used for calibration and bump testing of portable multi-gas detectors designed to monitor toxic gases, combustible gases and oxygen concentration in industrial environments.
Supplied in a 66L disposable aluminum cylinder pressurized to 1150 PSI with a C-10 valve, this cylinder provides a reliable calibration gas source for routine detector maintenance and sensor verification.
