Paper Abstract

A new method of measuring the total scattering coefficient b of turbid water is described. The method is based on measuring the irradiance and radiance from a point isotropic source. It is shown that the method accuracy can be improved by using the empirical relations between b and some integral parameters of the scattering phase function. A simple scattering meter `Turbido' based on this method has been designed, patented, calibrated, and tested. The instrument is intended for in situ measurements of b and concentration of suspended particles C in tap and natural waters. In the red spectral region the measurement range of b is 0.18 - 18 m-1, C ranges from 0.3 to 30 mg/l. The advantage of the instrument compared with nephelometers is its simplicity and weaker dependence of its readings on sizes of suspended particles.
