More and more requests for quality assurance inspection on concrete buildings have been made in recent years. When a concrete building is repaired, rebuilt, or maintained, there is the potential problem of accidentally cutting a reinforcing steel bar, electrical conduit and wiring, gas pipes, or plumbing. To perform quality assurance inspection and avoid such an accident, “Handy Search” has been developed as a nondestructive search device that can sense deep in concrete buildings.

Features
Compact and weight saving

The integration of the main-body display with an antenna section makes the device compact. It weighs only 1.1 kg which enables you to operate it with one hand.

Search of both metallic and nonmetallic objects

The radar system makes it possible to search for nonmetallic items, such as vinyl chloride pipes and cavities, as well as metallic objects, such as reinforcing steel bars. (Only skillful operators are allowed to analyze the image data of non-metallic objects.)

Data maintenance and replay

A single search operation enables 15 meters worth of data to be saved and replayed.

Cable-less printing

Implementation of the IrDA function eliminates cable connection and enables the dedicated monochrome printer (optional) to print out data on the spot.

Real-time surface wave processing

The NJJ-95B quickly performs search operation since it can eliminate surface waves in real time. In addition to fixed surface waves, the NJJ-95B enables the setting of surface waves with data being searched, offering simple operation and high-accuracy search capability.

Reading/recording of the analysis cursor position

After the search operation, the locations and depths of reinforcing steel bars and the likes can be read and recorded by the XY cursor. (Up to 7 points)

 

Principles
Principle of Handy Search

This device radiates electromagnetic waves through a concrete surface and receives reflected signals from objects such as reinforcing steel bars, cavities, or other objects that have different electrical characteristics from concrete. Object location and depth are then displayed and recorded as image data.
