<p>An apparatus for measuring particles in liquid in which a laser beam (3) is projected into the liquid containing particles (2) to be measured which are caused to flow into a measurement zone (34) in a measuring cell (1), and light scattered from the particles passing through the measurement zone is received by the light receiving means (20, 21, 22) to measure characteristics of the particles. The light receiving means are disposed with its optical axis nearly perpendicular to the axis of projection of laser light. The arrangement is such that the flow of fluid in the measurement zone (34) approximates laminar flow in a short distance within the measurement zone. This arrangement assures a stable and precise measurement of the particles.</p> |
