Abstract: A flue gas analyzer device which can be held in one hand and which has a probe barrel for drawing in a gas sample with a pump, a thermocouple arranged in the probe barrel, and with a housing receiving a battery-powered evaluating and measuring device. A pump chamber, a condensate chamber, a condensate separator, and the probe barrel are arranged axially one behind the other in front of a handle of the pistol-shaped housing of the analyzer device. The gas sample is drawn in from the condensate chamber via an exchangeable filter device by the pump arranged in the pump chamber and is supplied for analysis to sensors arranged in the handle via a line.
