ZK-F900 Comprehensive Testing Instrument for Concrete Crack Defects

ZK-F900 Concrete Crack Defect Comprehensive Tester Application Industry

Using ultrasonic and microscopic camera technology, it is suitable for detecting internal defects, crack scale, and crack width of non-metallic materials such as concrete, graphite, nylon, and their components, as well as detecting the fullness of grouting at the bottom joints of prefabricated shear walls in prefabricated buildings.

Features

10 inch (1280x800) high brightness touch display screen, with a larger brightness of 400 nits, intelligent interactive operation interface, easy to learn and use, and convenient operation;

The body is made of ABS high-strength engineering plastic, which has high temperature resistance (based on actual reports), flame retardancy, and good impact resistance

4cm overall thickness, 1.8kg lightweight body, lightweight and easy to carry

Crack depth measurement is more detailed and reliable first wave algorithm

Support the detection of grouting fullness at the bottom joint of prefabricated shear walls in prefabricated buildings

There are three modes for automatic interpretation of crack width, manual interpretation, and manual interpretation using an electronic ruler

Trustworthy self calibration function, can be calibrated with a standard scale plate, easy to operate

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

Automatically read the first wave time and amplitude, display in real-time, and make the test results clear at a glance

The sound time line can be manually adjusted to avoid misjudgment, and the operation is simple and practical

During the testing process, existing test point waveforms can be arbitrarily overwritten or deleted

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

The defect handling software has excellent functions and supports assembly based image analysis

Scale processing software that automatically analyzes data and easily prints reports

The PC upper computer can customize reports, support data cloud transmission, and export images, txt, office and other formats
