ABSTRACT:
An apparatus for the measurement of particulate scattering in fluids which is particularly suitable for low particulate concentration. The apparatus includes a housing with a cuvette for confining the fluid containing the particulate to be measured placed substantially at the center of the housing. A collimated light source provides a beam directed along an axis for illuminating the contents of the cuvette, and a light sensitive detector for receiving light scattered due to particulates along a selected axis. Surrounding the detector are a pair of equidistantly spaced baffles, of cylindrical or spherical configuration, which have a pair of aligned apertures centered about the scattering axis, and nonreflective facing surfaces.
