An apparatus for inspection of fluids having a fluid analysis cell with a cavity
therein enclosed by two light transmitting windows and having a spacer member fixedly
positioned therebetween which provides a fluid analysis chamber of fixed pathlength
where fluid flows by the windows and preferably wherein the flow laminar and at
a uniform shear to provide accurate color measurements. Light transmitting and
receiving probes are positioned adjacent to the viewing windows and wherein the
faces of each probe are contiguous and flush with the viewing windows but are separated
from the flow by the viewing windows, so that transmission measurements can be
taken orthogonal to the direction of flow. The apparatus is particularly useful
in the manufacture of dispersions and tints used in the manufacture of paints,
so that the color of material being made can be accurately matched to a standard
color in the wet state with confidence that the color will match in the dry state.
