Description
Overview
GAOTek ultrasonic concrete crack detector is used for testing concrete strength by ultrasonic rebound comprehensive method and detect concrete crack depth. It has a function to take automatic readings and photos of crack width of concrete structure.
Features
- Full touch screen operation, simple and convenient, stable and reliable
- Large-size high-brightness LCD display (8 in, 1024 x 768)
- Brand new operation interface, easy to learn and use
- Low power consumption design, continuous working time is more than 8 hours
- The ultrasonic rebound comprehensive method integrates 4 major functions strength measurement, lack measurement, depth measurement, and width measurement
- Automatic interpretation of the first wave sound time and amplitude, real – time display, and test results at a glance
- The sound timeline can be adjusted manually to avoid mis judgment, and the operation is simple and practical
- During the test, the waveforms of the stored measurement points can be played back, overwritten, and deleted at will
- U disk dump data, support software upgrade through U disk
