Abstract:
1. A detector comprising: a housing, the housing carrying a sensor and a display device; a first coupling element carried by the housing; an input/output probe comprising two internal substantially parallel channels separated by an internal solid divider, which isolates inflowing ambient air from outflowing air and directs the ambient air toward the sensor and outflowing air away from the sensor toward an outflow port; a second coupling element carried by the probe, where the second coupling element directly and rotatably engages the first coupling element to releasibly couple the probe directly to the housing, where the probe directs inflowing ambient air to the sensor in the housing, and, outflowing ambient air from the sensor in the housing, and where the sensor is selected from a class which includes a gas sensor, a temperature sensor and a humidity sensor.
