A series of instruments (structuroscopes) assigned for determining various characteristics of materials and products on the basis of the coercive force is described. Main technical characteristics of three types of the instruments are given. The last and most perfect modification is KRM-Ts-K3 instrument. It is provided with a self-contained power supply and has a wide measurement range. It has an internal memory for 4096 measurements and can be connected to a personal computer. Specially designed program software makes it possible automatically to construct graphs. Examples of graphical representation of the measurement data are demonstrated for two- and three-dimensional reproduction of the results.
