The Cross Hole Analyzer may evaluate the quality of the concrete of deep foundations by the Single Hole Sonic Logging (SSL) method, in addition to performing Crosshole Sonic Logging (CSL). The CHAMP-XV consists of a main unit with 60 GB internal solid state drive (SSD) and Windows 7 OS, transmitter, receiver, two independent depth measuring devices, a tripod for assembling the test, and the powerful software CHA-W.

Augered cast-in-place (ACIP) and Continuous Flight Auger (CFA) piles, as well as small drilled shafts, are prepared for the SSL test by installation of one single PVC tube in their center. During the test a transmitter and a receiver are lowered down the tube. A high frequency signal is sent from transmitter to receiver, scanning the entire length of the shaft. The transmitters and receivers are available with cables of various lengths.

The attractive enclosure of the CHAMP-XV is still light and small, but its color touch-screen display is 5 cm larger than the previous model and visible in all lighting conditions. The replaceable internal battery designed to last an entire day of normal testing, frees the tester from a power source, allowing easy movement between piles. Essential analysis is performed in the field in real time.

Field data transferred to a computer through USB ports, and is further analyzed by the CHA-W software, which outputs graphs such as First Arrival Time, Wave Speed, Waterfall Diagram and Energy Plot, and aids in test report preparation.

The CHAMP-XV meets or exceeds the specifications for cross-hole sonic logging required by D6760 Standard Test Method for Integrity Testing of Concrete Deep Foundations by Ultrasonic Crosshole Testing.
