PURPOSE: A device for particle sampling and dilution is provided to simplify the construction of a system for measuring a number of particles of high concentration generated at a high temperature and precisely measure the particle number in real time. CONSTITUTION: A device for particle sampling and dilution includes a main body(10) having an opened top part, a lower part formed with a suction hole, and an inner bottom part formed with an upward protrusion part for extending the suction hole to an upper end, at least more than one conduit(20) positioned on the main body, a coupling element(30) to be coupled at an upper part of the main body, a mixing tube(40) incorporated in the main body and communicated with the suction hole, the mixing tube having a lower end part contacting an outer surface of the protrusion part for forming a flow channel and formed with one or more grooves slanted inwardly, an elastic element(50) for continuously contacting a lower end of the mixing tube with the protrusion part, and a control element(60) for pressing the upper end part of the elastic element and coupled with the coupling element.
