<p><P>PROBLEM TO BE SOLVED: To provide a chromaticity and turbidity meter that can make a detector compact. <P>SOLUTION: There is provided the chromaticity and turbidity meter that makes light from a light source incident on a liquid tank comprising a measurement cell and a comparison cell at the same time, and measures chromaticity and turbidity on the basis of transmitted light beams transmitted through the measurement cell and the comparison cell. The liquid layer includes a transparent closing plate which is a columnar transparent body having two holes of different depth formed in one side face to have their centers at a predetermined distance from each other and also to have their side faces put one over the other, and has the two holes closed and the same thickness. A hole of deep depth between the two holes, the transparent closing plate, and a s pace formed to a thickness up to the other surface of the transparent body is defined as the measurement cell. A hole of shallow depth between the two holes, the transparent closing plate, and the space formed to a thickness up to the other surface of the transparent body are defined as the comparison cell, and light beams transmitted through the measurement cell and the comparison cell are received by an optical detector having the same performance. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
