Test items

 

This product is based on elastic wave detection technology, uses a professional

microphone as a receiving device, and uses a mature IE algorithm for fast imaging

analysis. The product can be used for non-destructive testing of concrete

structures (which are larger than the contact surface of the microphone), internal

defects or under-thickness. Typical applications are lining quality testing. At the

same time, based on the radar waveform scanning, the host has developed a

spectrum analysis scanning function, which greatly improves the accuracy and

efficiency of field detection and judgment.

 

 

 
 

Contactless:
Using industrial pickups, can achieve rapid movement detection and improve detection efficiency;


Good stability:
Avoids the resonance frequency shift caused by contact, which greatly improves the repeatability and

stability of the traditional IE method;


Powerful detection:
Detects defects on concrete surface / deep layer, such as voiding, non-compactness and thickness;


High detection accuracy:
It is less affected by the test surface and is not affected by the reinforcement;
The resolution and accuracy of defect / thickness detection are greatly improved compared to

traditional geological radars;


High detection efficiency:
Real-time drawing of contours of waveforms, spectra, etc. The determination of defects is simple and

clear, and results can be produced on the spot;
Combined with AI (Artificial Intelligence) determination, defects and types can be automatically

identified.
