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

Performance

High efficiency testing.  Lifting speed is more than 60m/s(point distance:20cm)

Display the test data graphically.  User can watch analyzed result directly

Fast and precise automatic judge the sound parameters.  Real-time wave display assures test efficiency

Humanized software design.  Software design applies to user and construction plant. Its help information ensure user handle easily

Link the rebound apparatus directly.  Detect strength of concrete by ultrasonic-rebound combine method with linking rebound apparatus directly, and get strength of concrete in time. The function has applied for national patent

Being sensitive to receive signal. Can receive signal more than 10m in concrete without defects

Can supply smooth power to radial energy transducer without external power

Standard USB storage with big capacity

Interior lithium battery supplies power for apparatus working more than 6 hours

Portable, small, light apparatus (1.75kg)

Extending function: testing thickness of concrete by impacting echo method.

Professional and powerful Windows system analysis software. It can export the data to Excel or Word for advanced analysis
