CJ-10 Nonmetal ultrasonic detector
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 defects of one hole by one trigger two receive.
☆ Testing dynam performance of geotechnical
investigation,rock,concrete etc.
Specification
☆ Technology code for testing of building foundation piles JGJ 106
—2003
☆ Technical Specification of Dynamic Pile Tests for Highway
Engineering JTG/TF81-01-2004
☆ Technology specification for inspection of concrete defects by
ultrasonic method CECS 21: 2000
☆ Technical specification for geotechnical investigation method
GB50021—2001
Performance
☆ High efficient testing. Lifting speed is more than 60m/s.( 20 cm
distance ).
☆ Display the test data graphically. User can watch analyze result
directly；
☆ Fast and precise Automatic judge the sound parameters. Real-time
wave display to assure test efficiency;
☆ Humanized software design. Software design apply to User and
construction plant. its help information ensure user handle easily；
☆ Linking the rebound apparatus directly. Detecting strength of
concrete by ultrasonic-rebound combine method with linking rebound
apparatus directly,and get strength of concrete in time. The
functions apply for national patent.
☆ Being sensitive to receiving signal. Can receive signal more than
10m in concrete without defects
☆ Can supply smooth power for radial energy transducer needless
external power.
☆ Standard USB storage with big capacity.
☆ Interior lithium battery supply power for apparatus work more
than 6 hours.
☆ Portable, small, light apparatus (1.75Kg).
☆ Extending function for testing thickness of concrete by impacting
echo method.
☆ Professional and powerful analysis software on windows system. It
can export the data to Excel or word for advanced analysis
