GTJ-R800 Steel protective layer tester
Usage overview
The steel protective layer measuring instrument is a portable non-destructive testing instrument, which can be used for the detection of the construction quality of reinforced concrete structures. It can measure the position of the steel bars on the concrete surface, detect the thickness of the steel protective layer and the diameter of the steel bars. In addition, the magnetic properties inside the concrete structure can also be The position of the body and the conductor are detected, such as the internal cable of the wall and the plumbing pipe. The pre-construction detection can effectively avoid damage to these facilities during construction and reduce accidents.

Features
※ The thickness detection mode displays the position of the reinforcing bar intuitively and accurately, and displays the thickness and the spacing of the reinforcing bars at the same time;
※ The thickness detection mode can automatically store the thickness and spacing, and the detection efficiency is greatly improved;
※ Waveform scanning mode visually displays the distribution of steel bars, making inspection and analysis of dense steel bars more intuitive;
※ Waveform scanning mode displays the thickness and spacing of the protective layer of the steel bar.
※ It can detect the middle position of two steel bars, aiming frame and indicator light, which is convenient for punching and core;
※ The instrument automatically stores the calibration value to achieve fast measurement, eliminating the trouble of each calibration;
※ Borderless grid/section scan, waveform scan can measure up to 6m in length;
※ TF card storage, large capacity, intuitive and convenient transmission;
※ 2.8 inch high resolution color LCD screen;
※ One-piece design, small size, light weight, easy to carry;
※ PC professional data analysis software, data processing and report generation is easy to complete;
