Product Description

Purpose
The detector is designed to reveal cracks, porosity, inadmissible thinning and other continuity violation of inner and outer protective coatings on metallic products with application of pulsed high voltage while an electric spark is fixed by the device in the place of continuity violation or inadmissible thinning.
