Japan Radio Radar Detection Device (Reinforced Bar Detector) RC Radar Handy Search NJJ-200k - A radar specialty store where you can purchase the detection device at a reasonable price!
This is a professional electromagnetic wave radar method rebar detection device (buried object detection device) with the world's first wireless display and operation unit. It is characterized by its deep exploration depth among electromagnetic wave radar devices, capable of investigating concrete interiors up to approximately 450 mm deep.
Three operation modes that cater to specific needs:
● Normal Mode
Similar to conventional methods, this mode allows the user to check exploration images at hand through handle operation.
● Handle-less Mode
By removing the handle, it enables exploration in narrow spaces, such as piping areas, which were not accessible with conventional devices.
● Extension Mode
By attaching the included operation rod, it allows exploration at heights that were unreachable with conventional devices during scaffold or gondola work (exploration images can be checked at hand).
The NJJ-200 excels at detecting deep buried objects; however, compared to the NJJ-105, it tends to have more noise in reflection images for shallow buried objects, which may lead to the possibility of technicians overlooking reflective materials. Therefore, for detecting PVC pipes, CD pipes, voids, and small boards at depths of around 50 mm, the NJJ-105 is more advantageous.
*Generally, it is difficult for those who are not experienced in exploration to detect deep buried objects at depths greater than 20 cm.
