G7 Multi-gas Cartridge Sensor Options
Updated December 1, 2023.
The G7 multi-gas cartridge configuration supports two, three, four or five gas sensors. Support for five gases is specifically available with the introduction of a dual-toxic gas carbon monoxide and hydrogen sulfide (COSH) sensor.
The G7 multi-gas cartridge features four sensor positions. 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 one must use a dual-toxic carbon monoxide and hydrogen sulfide (COSH) sensor.
Each sensor is assigned a one-character sensor code that helps you select the correct part number. The following table describes the gas sensor types and the associated sensor codes available for each sensor position.

To select a gas cartridge sensor configuration
It is important to verify that the configured gas sensor types are compatible with your G7 device. For more information, refer to G7 and G7 EXO Sensor Incompatibility List Support Article.
