Wireless Elastic Wave Measuring Instrument developed

Kim Il Hyok, lecturer of the Faculty of Resources Probing Engineering, has developed the wireless elastic wave measuring instrument which is widely used in practice.

This instrument is used to rationally determine the covering layer of a waterway tunnel by measuring the strength of the bedrock.

Newly developed elastic wave measuring instrument is composed in the form of radio system and graph display and sensors are installed so as to serve as a measuring duster in any position without confusion. Therefore it is very fast and measuring work is done conveniently and the best thing about this instrument is that it has no telegraphic interruption and noise.
