Product Description
High-Capacity 4-Gas Calibration Gas for Detector Maintenance Programs
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 10 ppm, Carbon Monoxide (CO) 300 ppm, Methane (CH₄) 1.45% (58% LEL Pentane Equivalent), and Oxygen (O₂) 15.0% 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 levels in industrial work environments.
Supplied in a 120L disposable aluminum cylinder pressurized to 1050 PSI with a C-10 valve, this cylinder provides extended calibration capacity for safety departments maintaining multiple gas detection instruments.
