Detection of cracks, porosity, inadmissible thinning and other discontinuities of internal and external protective dielectric
coatings (varnish, paint, powder, film, bituminous and other dielectric coatings) by application of pulsed high test voltage and
fixing electrical breakdown in places of discontinuity or inadmissible thinning.
Features:
• High stability of test voltage on electrode;
• possibility to customize sensitivity;
• large set of replaceable electrodes for testing of products
with different purposes;
• digital display of test voltage on electrode;
• special electrodes for inspection of internal and external surfaces of pipes;
• quick battery change;
• possibility to recharge battery separately from the electronic unit.
