Automatic Hammer Tapping Void Detector EC-1050
It is a non-destructive testing instruments fro building inspection from P, which can get rid of the traditional “hammer tapping” method and detect area of hidden void in a more scientific way!
By using this Automatic Hammer tapping Void Detector, the following defects in walls and slabs can easily be detected so that the falling hazards can be avoided with appropriate repair action taken: - Tile debonding; - void or delamination in concrete.
Principle of Working
The hammer on the detection unit will hit automatically. The vibrating sound from the tile or concrete being hit will be collected by the microphone, and analyzed. The state of tile bedding or concrete in zone depth of 40mm (for concrete face without tile finishes) will be identified with result displayed in different LED lights:

Green Light –Sound Concrete
Tile in good condition without debonding;
Concrete without void nor delamination |
Yellow Light –
Minor Spalling
Tile bedding condition needs attention;
Minor void or delamination in concrete |
Red Light –
Major Spalling
Tile debonded;
Void or delaminatio in concrete |
Features:
