DILUTION EQUIPMENT FOR WATER QUALITY MEASUREMENT AND DILUTION METHODS

Abstract

The present invention relates to a dilution apparatus for water quality measurement for preparing sample water by diluting a standard solution with dilution water, the apparatus comprising: a container (10); a standard solution supply unit for supplying said standard solution to the container; a dilution water supply unit for supplying said dilution water to the container (10); a circulation unit for circulating the water in the container; an outlet unit for allowing the water in the container to flow out; and a pressure sensor (9) for detecting the water level in the container, wherein said outlet unit includes a pump (14), and said water is made to flow out of the container (10) by gravity in a state where said pump (14) is stopped.
