The apparatus by the microcomputer control. Mixing blades by special Constant speed motor drive to 200r/min rotational speed, mixing blades rotate in the sample resistance moment by computer conversion to KU value (Krebs K rebs) units (KU) generated 200 r / min rotational speed required to load a logarithmic function, the general used for the Brush andviscosity) said. The operator simply mixing blades into the sample to the provisions of the depth, you can directly from the device to read the samples corresponding to KU value, CP (cps) g (grams).
