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, the plumbing pipe, etc., and the detection before construction can effectively avoid damage to these facilities during construction and reduce accidents.

| Features | |||||
| 1 |
The thickness detection mode displays the position of the reinforcing bar intuitively and accurately, and simultaneously displays the thickness and the spacing of the reinforcing bars; |
||||
| 2 |
The thickness detection mode can automatically store the thickness and spacing, and the detection efficiency is greatly improved; |
||||
| 3 |
The waveform scanning mode visually displays the distribution of steel bars, which makes the detection and analysis of dense steel bars more intuitive; |
||||
| 4 |
The waveform scanning mode simultaneously displays the determined thickness and spacing of the protective layer of the steel bar; |
||||
| 5 |
It can detect the middle position of two steel bars, aiming frame and indicator light, which is convenient for punching and core; |
||||
