METHOD AND INSTRUMENT FOR MEASURING FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a fine particle measuring instrument capable of easily and inexpensively acquiring a plurality of fine particle images photographed with identical timing. SOLUTION: The fine particle measuring instrument is equipped with a flow channel pipe 10 equipped with a measuring region 12 having light transmission properties and permitting a fluid containing fine particles to pass; a supply means 14 for supplying the fluid to the flow channel pipe 10; a plurality of imaging means 20 and 30 for photographing the inside of the measuring region 12 to acquire a plurality of fine particle images; and a control means 50 for controlling the operations of the supply means 14 and the imaging means 20 and 30. The control means 50 is constituted so as to take a plurality of the fine particle images at the same time, in a state where the flow of the fluid in the measuring region 12 is temporarily stopped.
