Description
Purpose
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.
Features
— inspection of coatings on metal and concrete backing;
— test width up to 1 meter;
— device grounding anywhere on the roof;
— adjustable output voltage range: 4–40 kV;
— thickness of tested coatings up to 25 mm;
— digital display showing voltage on electrode;
— high stability of voltage on electrode;
— adjustable sensitivity;
— quick battery replacement;
— battery charging in the device or separately while using the device (two batteries in the delivery set);
— high safety due to pulsed operation mode;
— large selection of replaceable electrodes for different purposes;
— small dimensions and light weight;
