Field of use
U5700, multi-channel ultrasonic detector, is the perfect device for Cross-Hole acoustic wave transmission method. This instrument is specifically designed for testing piles foundation integrity by using the acoustic wave transmission method integrated with the unique multi-channel self- emission / self-receiving function. It also enables the concrete pile all-profile test with only one lift (3 o 4 acoustic testing pipes embedded), which makes the detection process more efficient and simpler.

Available functions:
1. Cross-Hole 4 channels, automatic encoder;
2. Measure concrete resistance 25/50KHz;
3. Localization and Mapping of defects inside the concrete component;
4. Measuring the crack depth.

• Testing 3 or 6 profiles per lift. The lifting speed > 60 meters per min (5 points per meter);
• Gains and delays are adjustable for evry channel at any time, it ensures the data accuracy and reliability;
• Display all 6 profile information on one screen, thus making the quality of the entire rebar pile clear;
• 4 radical transducer part with different colors, makes simple operation convenient and efficient;
• During testing, you can adjust internal test point at any time and do “encryption” test point for important key parts;
• Can switch viewing bar graph, wave train graph, Depth curve, and record user’s use habits;
• Horizontal test, inclined test, retest, and finer increment testing multi modes, allow you to have an accurate identification of pile shaft defects;
• Built-in mass SSD (solid state disk) and mass lithium battery are perfect for field work;
• Data transfer trough U disk. Fast and convenient;
• Built-in GPS orientation module, can get the GPS information of every foundation pile and save to data files of detection;
• Built-in WIFI module, LAN access through wireless routing, it make data transmission more conveniently and quickly;
• Very high signal strength that allows you to perform surveys over long distances. Particularly suitable for the control of industrial buildings;
• Low frequency sonic survey (25KHz);
• Automatic gain control;
• Autosaves. fast and intuitive navigability;
• LCD color touchscreen;
• Internal high capacity Lithium battery;
• USB port for transferring data from the internal memory;
• Small size and light weight make it very easy to transport on the construction site;
• Professional software for data processing and test reports creation.
