グ装置。[Scope of claim for utility model registration] A sampling probe disposed in a first flow path through which a fluid to be measured flows, a second flow path through which a dilution fluid flows, and a communication flow connecting the sampling probe and the second flow path. a differential pressure detection means for detecting a difference between the static pressure in the first flow channel and the static pressure in the sampling probe; and adjusting the amount of diluent fluid based on the value detected by the differential pressure detection means. A supply control means for controlling the difference between the static pressure in the first flow path and the static pressure in the sampling probe toward zero by supplying the fluid in the middle of the communication flow path. Fixed rate sampling device.
