Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of portable flue dust direct reading test instrument, including feeler lever 1, heater 2, measuring chamber 3, cigarette
Dust sensor 6 and aspiration pump 4, the feeler lever 1 include that probe 12, cartridge heater 11 and admission line 10, the feeler lever 1 are integrated into
Type structure, the feeler lever 1 are connected by admission line 10 with heater 2；The heater 2 is the cylindrical shape of inner hollow, institute
It states 2 end of heater and is set as flat interface 22, inlet channel temperature controller 21 is equipped with inside the flat interface 22, it is described
Flat interface 22 extend into the position of measuring chamber 32/5；3 left end of measuring chamber is connected to smoke gas sensor 6, the measuring chamber 3
Right end is equipped with detector 31；3 right end of measuring chamber and flat 22 opposite position of interface are equipped with outlet pipe 41, it is described go out
