Abstract:
A measuring apparatus of sedimentation rate for determining the sedimentation rate of sediments, comprising:inclination holding means for holding a test container accommodating a liquid sample containing sediments in an inclined state, projecting means for projecting light to said test container, photo detecting means disposed oppositely to said projecting means across said test container, for detecting the light passing through the test container from said projecting means, and converting photoelectrically, light quantity change measuring means for measuring time-course changes of the photo detecting means output, and sedimentation rate calculating means for calculating the sedimentation rate of sediments in the test container on the basis of the result of measurement by the light quantity change measuring means; wherein said inclination holding means has a structure capable of holding a plurality of test containers differing in shape and size in an inclined state, and the sedimentation rate can be measured in a plurality of test containers differing in shape and size.
