摘要： The object of the present invention is to provide a particle counter which can accurately count the number of particles contained in fluid where the number concentration of particles is high. The particle counter includes a particle removing portion for removing particles contained in fluid at a predetermined rate, a sensor portion for counting the particles passing through the particle removing portion, and a particle number correcting means comprising a characteristic data memory and a digital signal processor for performing correction processing to the number of the particles counted in the sensor portion by using removal characteristics of the particle removing portion with respect to the particle diameter.
