Features

Introducing next-generation "High-resolution Handy Search"!

In recent years, the density of rebars is increasing to improve the durability of concrete structures, which is driving the demand for search equipment with higher resolution.
We developed improved search resolution in the horizontal direction and better search accuracy for shallow rebars and kept the popular performance (compact and lightweight) of the Handy Search NJJ-95B.

Principle

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.

Main Features

Higher resolution when searching horizontally

Possible to determine rebar at 40 mm intervals from 75 and 175 mm deep.

Higher definition when searching horizontally

Search definition improved from 5 mm to 2.5 mm intervals.

Compact and weight saving

The integration of the main-body display with an antenna section makes the device compact. It weighs only 1.2 kg which enables you to operate it with one hand.

Search of both metallic and non-metallic objects

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

Data maintenance and replay

Up to15 meters of data can be saved and replayed in a single measurement.

Cable-less printing

Cable-less connectivity makes it easy to print directly to the specialized black-and-white printer (option).

New Functions

Added new imaging process

Added average wave processing and user surface wave processing to the existing imaging processes (original,fixed, subtraction, manual, and peak).

Expanded depth display

Added wide-range display function that shows twice the measured depth.

Start-up state selection function

Added a function to store settings at shut down to save time when starting up for the next job.

Expanded depth calibration value

Possible to set calibration values at 0.1 steps from 2.0 to 20.0.
