Resonance defectoscopes (Descrydefect)

This method is based on determining the natural resonant frequencies of elastic vibrations excited by a product. (frequency 10.1 MHz). Resonance method determines the wall thickness of metallic and non-metallic products. This method can also identify areas of corrosive damage. View resonance method is spectrally-acoustic defectoscopy (Descrydefect).
