Abstract
A water quality meter is composed of a plurality of water quality monitoring meters including analyzing units for analyzing water samples introduced from a water distribution pipe, each analyzing unit analyzing the water samples and a measuring cell, and a liquid introducing unit integrated with the analyzing units, which is composed of a single member in which a plurality of fluid flow paths for feeding various types of liquid including the water sample into the analyzing unit are formed. Furthermore, the cells and the plurality of three-dimensional fluid flow paths formed in the single member are fabricated by a micro-fabrication technique using photo-curing resin.
