G7 Quad-gas Cartridge configuration is straightforward, supporting two, three and four gas options. In the future, the Quad-gas Cartridge will also support five-gas options with the upcoming introduction of a dual-toxic carbon monoxide and hydrogen sulfide (COSH) sensor.

Customers have the option to choose an oxygen sensor, a combustible gas sensor and up to three toxic gas sensors. To support three toxic gases, Toxic Gas Sensor 1 must use a dual-toxic hydrogen sulfide (H₂S) and carbon monoxide (CO) sensor, when it launches.

This article provides an overview of how you can select combinations of gas sensors. The G7 Quad-gas Cartridge features four sensor positions, each with a range of sensor options. Each sensor is provided a one-character designation that helps to select the correct part number.
