Introduction of Handy Search NJJ-200

We have introduced the rebar detection device using electromagnetic wave radar, Handy Search NJJ-200 by Japan Radio Co., Ltd.

The maximum measurement depth has been increased to 450 mm compared to conventional devices, and resolution has been improved by using a higher frequency (2100 MHz). The display screen can be detached from the main unit for use, enabling inspection of narrow areas such as under pipes that were inaccessible with previous models.

It meets the performance requirements for detection devices outlined in the Ministry of Land, Infrastructure, Transport and Tourism’s “Guidelines for Measuring Rebar Conditions and Concrete Cover in Concrete Structures by Non-Destructive Testing.”

We handle everything from creating rebar drawings to preparing reports.
