Determining paint sample volume characteristics with a sensor to emit and detect signals reflected from the sample and create data sets relating to the sample and a reference sample

摘要

596554 Disclosed is an instrument for measuring volume solids of a paint sample (34, 36). The instrument includes sensor means arranged to emit and detect signals reflected from the surface of the paint sample (34, 36) on a substrate (38). The detected signals are used to generates data sets consisting of data indicative of the position of the surface of the paint sample (34, 36) when wet (34) and when dry (36), and the position of a reference surface. The sensor means are located so as to be distanced from the paint sample (34, 36) for the emission and detection of the signals. The instrument also includes processing means for processing the data sets generated by the sensor means to determine the volume solids of the paint sample (34, 36).
