GTJ-RBL/GTJ-RBL+ 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
※ New upgrade, adopting three-proof shell design, waterproof,
dustproof and shockproof.
※ Large-screen high-resolution LCD screen with Chinese prompts on
the interface, the display content is more intuitive and more
intuitive;
※ Built-in large-capacity memory card, new upgrade of storage
capacity;
※ USB transfer simulates the host as a USB flash drive, and reading
data is as simple as a USB flash drive;
※ The thickness of the protective layer and the steel signal image
are displayed in real time, and the minimum value is automatically
locked;
※ Dual-range working mode effectively guarantees detection accuracy
and maximum detection depth;
※ The test data is automatically stored, and the results of
statistical analysis are provided on the spot to facilitate the
construction work;
※ Professional data analysis software makes your post-processing
and report production work easy.
