Claims

[Scope of utility model registration request]

A detector having pores formed narrow enough to allow the particles to pass through is immersed in a suspension containing particles, and the suspension is passed through the pores, and as it passes through, particles are suspended. A device for detecting particles based on a difference in impedance with a turbid liquid medium and counting their number or volume, which comprises a fluid control device communicating with the inside of the detector, an internal electrode 5 connected to a power supply circuit, and an external electrode. an electrode 6, two donut-shaped detection electrodes 8.9, each connected to a detection circuit and sandwiching the donut-shaped insulating disk 13 forming the pore, the inner electrode 5 and the outer electrode 6. a power supply circuit for passing a current between the detection electrode 8.9 and the detection electrode 8.9;
and a detection circuit connected to the particle measuring device for detecting particles based on an impedance difference between the particles and the suspension medium.
