Abstract: A system includes a gas detection device and an accessory device identification system in communicative connection with a control system of the gas detection device. The accessory device identification system is configured to receive data including identification data for at least one of (i) each of one or more associated accessory devices or (ii) an associated combination of accessory devices configured to be placed in fluid connection with the inlet of the gas detection device. The accessory device identification system is configured to identify at least one of (i) each of the one or more associated accessory devices or (ii) the associated combination of accessory devices (from the identification data received.

Abstract: A gas detection device for detection of one or more gas analytes in an environment includes a housing including an inlet via which gas to be sampled from the environment enters the housing, a control system within the housing comprising a processor system and a memory system in communicative connection with the processor system, and one or more gas sensors within the housing in fluid connection with the inlet and in communicative connection with the control system. Each of the one or more gas sensors is independently responsive to one of the one or more gas analytes. The control system is configured to control flow rate of gas from the environment through an accessory device assembly including one or more accessory devices in fluid connection with the inlet on the basis of data for the accessory device assembly in fluid connection with the inlet.
