Product Description
High-Capacity Quad Gas Calibration Mixture for Detector Maintenance Programs
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 to monitor toxic gases, combustible gases and oxygen concentration in industrial safety environments.
Supplied in a 120L disposable aluminum cylinder pressurized to 1050 PSI with a C-10 valve, this cylinder provides extended calibration capacity for facilities maintaining multiple gas detection instruments.
