Electrodes
-
Brush (fan) electrode
Electrode is designed to inspect dielectric coatings of complex profile.
-
Straight silicone rubber electrode
Designed to define places of continuity violation on insulating coatings.
-
Brush (hair) electrode
Designed to inspect dielectric coatings with complex profile and larger area.
-
T-shaped electrode
Used to test dielectric coatings of flat products.
-
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.
