Abstract: A method and an apparatus for determining colorimetric concentrations wherein the difference between the light absorption of a medium in two or more different wave-length ranges is measured by means of an automatic wave-length switching, whereupon the concentration of the medium is calculated in dependence of said difference and the absolute absorption of the medium in one of the wave-length ranges.

Abstract: An apparatus and method for measuring the content of material suspended in liquids or the turbidity of liquids by illuminating the liquid with a light source and a photo-electrical registration of the intensity of the reflected light comprising a tubular nozzle arranged to provide a jet of liquid. Said jet of liquid being illuminated through a gap substantially perpendicularly to said jet, whereupon the intensity of the light reflected from particles in said jet is measured at an angle to that at which the light falls.
