KEY FEATURES
Dramatically increase the speed and accuracy in detecting invisible delamination, voids and hollows below the surface of concrete, tile and natural stones, compared with tapping with hammers or dragging chains.
Use for non-destructive inspections of concrete slabs, parking garages, bridge decks, beams, tile, balconies and tunnels.
Changes in the sound of the sprocket teeth tapping the surface reveal the hidden defects.
Safer than climbing up and down ladders with a hammer.
Helps avoid wrist strain from repetitively tapping with a hammer.
Also useful for non-destructive sealant adhesion testing.
The body of the DDT Tool is a solid aluminum extrusion, threaded to accept a standard painter’s extension pole or broom handle (Albion part # 876-1 or 876-2).
There is also a slot (with a set screw) for a marking crayon or paint pen.
The wheels are hardened steel, mounted on precision shoulder bolt axles, spring loaded for smooth turning and maximum auditory feedback.
