Zusammenfassung:	The utility model relates to a dew-point detecting device of continuous annealing furnace, comprising a sampling tube(1). The sampling tube(1) is respectively connected with a three-way tube(2), a four-way connector(5) and a pump(6). The four-way connector(5) and the pump are arranged inside a gauge box(7). A dew-point probe(9) is arranged between a detecting room(8) which is connected with one outlet of the four-way connector(5) and a dew-point device(10). One outlet of the four-way connector(5) which is positioned between the pump(6) and the four-way connector(5) is provided with a temperature sensor(11). A temperature control device(12) is connected with the temperature sensor(11). The outer layer of the sampling tube(1) is coated with a hot mixing band(14). One end of the hot mixing band(14) is fixed on the outlet of a heating furnace(15), while the other end is fixed on an interface of the four-way connector(5). The two sides of the heating furnace(15) are provided with a protective gas tube(17), and the protective gas tube(17) is provided with a humidity controller(18).
