The results of the measurements are transmitted to a computer control device wherein the results of the measurements obtained simultaneously in both measuring systems are compared. The device according to the invention is characterised by having two resonant measuring systems /A/ and /B/ coupled with one another by means of a computer control device /C/, and one of the resonant measuring systems /A/ has an electromagnetic radiation generator /2/ of microwave frequencies, while die other resonant measuring system /B/ has an electromagnetic radiation generator /7/ of a frequency markedly lower than the microwave radiation frequency.
