The Cross-Hole Analyzer determines the quality and consistency of the concrete of drilled shafts, slurry walls, bored piles, cast-in-situ piles and other types of concrete foundations. PDI’s Cross-Hole Analyzer (CHAMP-Q) is ideal for testing up to six profiles in just one pull, saving time and money. CHAMP-Q has four color-coded cables for easy identification of each transceiver probe. The CHAMP-Q meets or exceeds the specifications of ASTM D6760 and several other cross-hole sonic logging codes and standards.
