WCH-4 introduces a new concept of device for cross-hole surveys on foundation poles. More than an equipment in its traditional sense, WCH-4 is a modular wireless device for foundation pole cross-hole surveys and its core are the motorized electronically controlled reels on which are mounted high power probe holes for cross-hole surveys on foundation poles, diaphragms, and all cement or concrete infrastructural works which can be tested by cross-hole methodology, that is sloping down through pipes specially arranged when thrown and then filled with water.
Each reel of WCH-4 system is equipped with a 60 mt cable motorized probe, and with all the electronics which automatically manages the probe during the descent / ascent of the probes (cross-hole) and data saving.
Due to Panasonic Rugged Tablet 10.4", and the almost total lack of material wiring, settings, measures management in addition to display and interpretation of the data acquired is easy and immediate. In the direct analysis mode each wave emitted by the inner generator is fully displayed and it is also possible to change display parameters to further facilitate reading of the crossing speed and the presence of defects in the material investigated.
