Zk-U91 concrete ultrasonic testing instrument

Application Industry: Concrete strength testing, internal defect, surface crack scale, and width testing in the construction industry; Testing of acoustic parameters and mechanical properties of non-metallic materials such as rock mass and concrete

Function Features

Ultrasonic rebound comprehensive method integrates four functions: strength measurement, defect measurement, depth measurement, and width measurement.

Automatically read the first wave time and amplitude, without the need for manual interpretation, and display the detection results directly

10 inch high brightness touch screen display, intelligent interactive operation interface, easy to learn and use, convenient operation

4cm slim and light body, lightweight and easy to carry

The sound time line can be manually adjusted, and the data correction and detection results are more accurate

During the testing process, it is possible to replay, overwrite, or delete the waveforms of existing test points at will

Low power design, continuous working time greater than 8 hours

U flash drive for data transfer, supports software upgrades through U flash drive

The PC one-to-one analysis software has excellent functions, making data analysis, processing, and printing reports easy to complete
