The multi-channel ultrasonic tester is the perfect device for cross-hole acoustic wave transmission method. This instrument is specifically designed for testing the pile foundation integrity by using acoustic wave transmission method, and contains the unique multi-channel self-emission and self-receiving system. It also enables the all-profile test of concrete pile with only one lift (3 or 4 acoustic testing pipes embedded), which makes the detection process more efficient and simpler.

The principle of ultrasonic transmission method for detecting concrete quality is to embed several acoustic pipes in the pile as the channel for ultrasonic receiving and transmitting transducers. During detection, a transmitting probe for transmitting ultrasonic wave is placed in one tube, and a receiving probe for receiving ultrasonic wave is placed in the other tube. The two probes are lifted synchronously from the bottom up, and the instrument records the acoustic characteristics of ultrasonic propagation in the concrete measuring surface composed of two tubes. According to the arrival time, amplitude, frequency change and waveform distortion of the wave, through analysis and treatment, the concrete quality, the nature, size, spatial position and concrete uniformity of the existing defects can be determined.
