Description of Equipment
This equipment is indispensable for repairing/rebuilding and maintaining reinforced
concrete structures using its accurate and speedy diagnostic technology.
The Handy Search concrete internal probe vehicle, NJJ-95B, (hereafter called this
radar) radiates electromagnetic waves through the surface of concrete and receives
reflected signals from objects found inside such as reinforcing steel bars, cavities, or
other objects that have different electrical characteristics from concrete. Object
position and depth are then displayed and recorded as image data.
CAUTION
Making a judgement on the search results considering the depth sensing
capability of the NJJ-95B:
Since the depth sensing capability of the radar is subject to the conditions of
the object of investigation, judging the search results with no consideration of
the depth sensing capability may cause the accidental cutting of rebar.
