The detector is designed specifically to detect flaws in waterproof coatings on conductive substrate (e.g. steel, concrete, aluminium foil) of roof systems with the application of high voltage while an electric spark is fixed by the device in the place of the fault.
This dry method does not require wetting the waterproof membrane surface before the test, which allows to inspect both flat and complex-shaped surfaces with a significantly higher speed.

The device can be completed with additional rechargeable batteries and the following replaceable electrodes:
— T-shaped electrode of small dimensions, brush (fan) electrode, flat rubber and hair electrodes with inspection zone from 50 to 400 mm;
T-shaped tubular electrode (mountable)
Designed to inspect flat dielectric coatings, usually large areas like the roofs of buildings. Manufactured from 200 to 1000 mm. Since it is mountable, the width is adjustable.
Brush (fan) electrode
Designed to inspect dielectric coatings of complex profile.
Brush (hair) electrode
Designed to inspect dielectric coatings with complex profile and larger area.
Used to test dielectric coatings of flat products.
Silicone rubber electrodes
Designed to define places of continuity violation on insulating coatings.
Straight silicone rubber electrodes: Suitable for testing coatings on larger flat surfaces.
Special electrodes can be made according to customer’s own specification.
