APPARATUS FOR MEASURING CONCENTRATION OF SUSPENSION LIQUID

摘要

PROBLEM TO BE SOLVED: To provide a concentration-measuring apparatus for a pulp suspension or the like which has a superior portability, and can substantially simultaneously continuously measure concentrations of a plurality of suspensions. SOLUTION: The apparatus has a measuring unit 2 which projects a laser to a suspension of a low concentration passing in a photocell 28 formed of a transparent material and measures the concentration of the suspension from a transmittance of the light. A clear water 24 as a comparison solution and a plurality of suspensions 21-23 can be sequentially supplied to the measuring unit 2 through a supply liquid dispenser unit 1 having a function of separately supplying one of the solutions.
