The CHUM (Cross Hole Ultrasonic Monitor) conducts high-resolution quality control of deep foundations using the Crosshole Sonic Logging (CSL) method. This technique transmits ultrasonic waves from a sender to a receiver through water-filled access tubes embedded in concrete. The wave's arrival time and energy indicate concrete quality. Ougan Cross Hole Ultrasonic Monitor features a 12-inch high-resolution display, WinCE OS, 4-channel control, Bluetooth connectivity, and real-time data upload. It supports efficient pile quality testing and precise analysis.
Built-in industrial instrument dedicated industrial control computer with a high-resolution 12-inch color lcd display for field use.
Based on the WinCE embedded operating system,stable and reliable,supports USB flash drive for system startup and recovery.
Fully laminated capacitive touchscreen.
Bluetooth wireless+wired connection depth counter.
Touchscreen operation,compatible with mouse and keyboard, built-in large analog input panel,supports Chinese.
Multiple sonic tubes forming a profile for one-time completion of detection.
Sampling while simultaneously displaying image maps (or waveform charts, wave velocity and amplitude curves,tables).
Adjustment of magnification, delay time, judgment threshold, and sampling step size is possible simultaneously during sampling.
Pause and rewind are available during sampling, enhancing the pre-sampling trial function.
Customization of the data acquisition software window position and interface colors is possible.
Supports data upload to multiple platforms.
The analysis software supports the Windows operating system, featuring a unified style,user-friendly interface, convenient operation, rich functionality,standardized processing, and automatic generation of report charts. It also provides interfaces for exporting to Word, Excel, BMP images, and more.
