Abstract:
The invention relates to a measuring method for measuring the properties of a powder or granular sample (1) from the surface information of the sample. According to the method the sample is leveled for the measurement, at least one image of the surface of the sample (1) is taken and the properties, such as the grain-size distribution, of the sample (1) are determined by processing the information material by calculation. According to the invention, the sample (1) is made to be supported on a transparent sample plate (2, 13, 14, 15) and an image is taken through this sample plate (2, 13, 14, 15).
