Product Description
High-Capacity 4-Gas Calibration Gas for Multi-Detector Maintenance
This 4-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 used for calibration and bump testing of portable multi-gas detectors that monitor toxic gases, combustible gases and oxygen levels in industrial environments.
Supplied in a 120L disposable aluminum cylinder pressurized to 1050 PSI with a C-10 valve, this larger cylinder provides extended calibration capacity for facilities that maintain multiple gas detection instruments.
