NJC71 Ultrasonic Automatic Pile Testing System - NJC71

Purpose
Testing of building foundation piles by cross-hole sonic logging;
Inspection of concrete defects by ultrasonic method, such as uncompacted, cellular, hole area.
Detecting strength of concrete by ultrasonic-rebound combine method
Detecting strength of concrete crevice by ultrasonic-rebound combine method
Detecting defects of one hole by one trigger two receives
Testing dynamic performance of geotechnical investigation, rock, concrete etc
