PROBLEM TO BE SOLVED: To provide a compact water-quality measuring apparatus having no mechanical operation section. SOLUTION: In the water quality measuring apparatus for measuring the characteristics of measured liquid based on the absorbance of the measured liquid in a cell, light from a light source 1 is made to come into the cell 3, the light having transmitted through the cell 3 is made to come into a light condensing optical means 4, the light having reflected and condensed by the light condensing optical means 4 is made to come into a first detector 5, the light having reflected and condensed by the light condensing optical means 4 and then having transmitted through the cell 3 is made to come into a second detector 6, and the absorbance is measured based on the ratio between the output from the first detector 5 and the output from the second detector 6. The turbidity and chromaticity of the measured liquid is measured. COPYRIGHT: (C)2008,JPO&INPIT
