Product Description
Quad Gas Calibration Mixture for Portable Gas Monitors
This 4-gas calibration gas 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 to calibrate and verify portable multi-gas detectors that monitor toxic gases, combustible gases and oxygen levels in industrial work environments.
Supplied in a 66L disposable aluminum cylinder pressurized to 1150 PSI with a C-10 valve, the cylinder provides a portable calibration source for routine detector maintenance and bump testing.
