GTJ-U950 non-metal ultrasonic detector
Overview of use:
Acoustic transmission method for pile integrity testing; structural
concrete compressive strength, crack depth, crack width and defect
detection; continuous wall integrity testing; set pile, ultrasonic
rebound comprehensive method strength measurement, lack of
measurement, crack sounding and measurement The five functions of
the wide five are integrated. Geological exploration, rock
integrity, weathering evaluation test; mechanical properties of
non-metallic materials such as rock mass and concrete.
Features:
Automatic interpretation of sound parameters, real-time dynamic
waveform display;
High receiving sensitivity (high recognition ability for weak
signals, accurate detection of defect size and range);
Small size, light weight, easy to carry, dual channel, and strong
scalability;
Large-capacity rechargeable battery - long-lasting sequel, no
worries;
Intelligent processing software - practical, convenient and
powerful;
The depth recording wheel is dustproof and waterproof. At the same
time, it has wired and wireless connection, which is flexible and
convenient;
The first wave is positioned accurately, and the pile body defects
are restored in real time on site;
Wifi connection slit width function;
High-performance A8+DSP main control processing unit with 10.4 inch
industrial high brightness wide temperature LCD screen;
The transducer spool is designed with a current collecting ring,
and the signal cable is retractable to prevent the cable from being
twisted.
