Product Description
4-Gas Calibration Gas for Portable Detector Calibration
This 4-gas calibration mixture contains Hydrogen Sulfide (H₂S) 20 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 routine calibration and bump testing of portable multi-gas detectors used in industrial environments where accurate gas monitoring is critical for worker safety.
The gas is supplied in a 116L disposable aluminum cylinder pressurized to 1000 PSI with a C-10 valve, providing a reliable and convenient calibration source for maintenance teams and safety programs.
