Claim Text:
1. An instrument to measure the volume solids of a paint sample, the instrument comprising: sensor means arranged to scan both the surface of a paint sample on a substrate surface moving with respect to the sensor means and an exposed reference surface of the substrate along the same line during the same scan, and to emit and detect signals reflected from the surface of the paint sample and the exposed reference surface of the substrate along the line for generating data sets including data indicative of a position of the surface of the paint sample when wet and a second position of the paint sample when dry, and to detect the position of the exposed reference surface of the substrate, in which the scan line of the paint sample and the exposed reference surface of the substrate when wet is in the same location as the scan line of the paint sample and the exposed reference surface of the substrate when dry, the sensor means being located so as to be distanced from the paint sample for the emission and detection of the signals; and processing means for processing the data sets generated by the sensor means to determine the volume solids of the paint sample.
