PROBLEM TO BE SOLVED: To prevent erroneous measurement caused by deterioration of a light emitting diode, a stain and a flaw in glass on a projection part and a photoreceiving part front face, and to cope with various sample liquids. SOLUTION: This turbidity measuring instrument is provided with the projection part, a sample cell through which light emitted from the projection part is transmitted, and a photoreceiving part for detecting the light transmitted through the sample cell, and is provided with a turbidity computing means for finding an absorbance based on a ratio between light intensities detected by the photoreceiving part when no measured sample liquid exists in the sample cell, and when the liquid exists therein, to compute the turbidity based on the absorbance. In the instrument, a plurality of measuring channels are provided, and a plurality of working curves are prepared by calibration to be stored in the respective channels. COPYRIGHT: (C)2004,JPO
