<P>PROBLEM TO BE SOLVED: To provide a water content measuring device that eliminates an effect of substances (solutes) that absorb light other than water (solution) contained in solution to accurately measure water content. <P>SOLUTION: Water content (volume fraction) and concentration of solutes are determined by referring to a graph indicating a coefficient of absorption at temperature T1, a coefficient of absorption at temperature T2, and a change in a coefficient of absorption of ultra pure water for 1°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
