1.1 Brief Introduction

Thefirst generation portable rebar integrated detector RL31 uses anelectromagnetic induction method, which can detect the rebar location and coverthickness & diameter accurately, store, transfer and analyze the real timetest data. The model RL32X is the pinnacle of work with the modern simpledesign, incorporating the handy & durable features and sophisticatedelectronic technology.

RL31series rebar detector is mainly used to test the location, distribution,direction, the thickness of rebar and the diameter of cover in concretestructure such as walls, columns, beam-slabs etc. It can also detect thelocation of pipelines and metal embedded parts. The multiple coil structuredesign make it more accurate＆responsive and higher resolution.

1.2 Application Range

(1). Testing the location,distribution, direction, and diameter of the rebar and the thickness of coverin concrete structure projects.

(2). Inspecting and acceptingconcrete structural construction quality.

(3). Evaluating the quality ofconstruction.

(4). Establishing the location ofrebar for drilling, cutting and coring operations.

(5). Testing the distribution anddirection of electric cables, pipelines and metalwork inside walls and floors.

(6). Testing the quantity of rebarwhen evaluating and developing the old structure, such as installation offurniture and air-condition.
