An apparatus for inspection of fluids, particularly dispersions and tints, having a fluid analysis cell with a cavity therein defining a fluid analysis chamber, fluid inlet and outlets extending from the cavity in opposite directions to enable fluid flow into and out of the analysis chamber, and a light transmitting probe and a light receiving probe extending within the cavity juxtaposed from each other across the flow path in spaced apart relation, with the probes being movable relative to each other, thus providing a fluid analysis chamber having an adjustable pathlength and allowing flow across and around the faces of the probes for pressure relief of the fluid, to provide accurate color measurements. 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.
