Abstract: PURPOSE:To enable easy and continuous measurement of water quality even with respect to a sample water varying in the composition of pollution by determining a required coefficient through a 3-wavelength parallel radiation flux to determine the indicator concentration of a composed suspension. CONSTITUTION:A radiation detector section detects the dissipation of detritus and botanical plankton suspension materials A and B separated from a test water by a parallel radiation flux with the wavelength lambda1 in the infrared to long wave visible range and wavelengths lambda2 and lambda3 in the ultraviolet to short wave visible range from an emitting section 1. Then, an arithmetic section 12 containing a microcomputer calculates proportion coefficients alphaAlambda1, alphaBlambda2, alphaAlambda2, alphaBlambda2... of each wavelength corresponding to exponential concentrations PA and PB of the materials A and B while the proportion coefficients betalambda2 and betalambda3 of the indicator concentrations of dissolved organic substances are read out from a memory means. In addition, the difference is calculated about the wavelengths lambda1-lambda3 between the volume coefficient of a test water by the parallel radiation flux and the volume coefficient of water.
