摘要：Abstract The present invention provides a probe arrangement for a duct detector, the arrangement including a portion mountable to a duct; and a probe or probes, having one or more ports and extending from the mountable portion to extend into the interior of the duct to position the port(s) in the duct; the probe or probes being reorientable relative to the mountable portion in use, to reorient the port(s) relative to flow in the duct independent of an orientation at which the portion mountable to the duct. There is also provided a duct detector including: one or more inlets for receiving a sample of flow from a duct; one or more outlets for returning the sample to the duct; a detection region between the inlet and the outlet; the inlets and the outlets being configurable for flow in the duct to drive the sample flow through the detector for aspiratorless operation; and structure for receiving an aspirator for aspirated operation. There is further provided a duct detector including: at least one inlet port for receiving an air sample from a duct; at least one detection region; at least one exhaust port for expelling the air sample; structure defining a flow path between said at least one inlet port and said at least one exhaust port via a detection region, said structure defining the flow path including mounting structure configured to carry an aspirator in the flow path for enabling aspirated operation of the duct detector; and also configured to maintain integrity of the flow path when not carrying an aspirator to enable aspiratorless operation of the detector. There is additionally provided a duct detector including one or more inlets for receiving a sample of flow from a duct; a detector module for analysing the sample; a device for extracting power from the flow in the duct to generate electricity to power at least part of the duct detector.
