ABSTRACT:
Liquid mobility is judged by the steps of filling the specimen in a specimen chamber formed in a specimen bed made of a transparent material just up to the level of the upper surface of the specimen bed, of pressing a liquid-absorbent material keeper for keeping a liquid-absorbent material horizontally to make the liquid-absorbent material contact with the specimen bed from the upper side of the specimen chamber, and of continuously detecting an intensity of a scattered light coming from the specimen in the specimen chamber with an optical detector consisting of a light emitting source and a light receiver and being disposed on the side of the lower surface of the specimen bed while the liquid-absorbent material is forced to contact the specimen bed. The liquid mobility is grasped in a short period of time.
