Introduction

Pile  Integrity  Tester  With  Reflection  Wave  Method  is  an intelligent  and  portable  analyzer  for  pile  foundation  detection  with  such capabilities as signal acquisition, data analysis and processing, and  storage  and  output  of  results.  This  instrument  mainly  uses  a  reflected  wave  method  to  examine  the  shaft  concrete  integrity  of  various types of piles in order to determine the extent and location of defects in the pile shafts.

Composition of Instrument

Pile  Integrity  Tester  With  Reflection  Wave  Method  mainly  includes  a  host  machine,  sensors,  a  hammer  (or  rod),  Windows–based  analysis  and  processing  software  and  other accessories (such as U disk, manuals, etc.).
