An apparatus for the inspection of fluids, particularly paints, having a housing with a cavity and enclosed with a light transmitting window and having an insert member positioned in the cavity which provides a fluid chamber where fluid flows by the window and wherein the flow is laminar and undirectional. This provides a view area of the liquid whose color parameter can be accurately measured by a colorimeter of spectrophotometer. The apparatus is particularly useful in the manufacture of paints so that the color of the paint being made can be accurately matched to a standard color.
