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 detecting strength of concrete by ultrasonic-rebound combine method CECS 02:2005
Technical specification for geotechnical investigation method GB 50021-2001
Purpose
Testing building foundation piles by crosshole ultrasonic wave method .
Inspecting concrete defects by ultrasonic method, such as uncompacted place, cellular hole area
Detecting concrete strength by ultrasonic-rebound combined method
Detecting concrete crack depth by ultrasonic method
Detecting the wall defects of the hole by one transmitter and two receivers
Detecting the strength performance of geotechnical investigation, rock, concrete, etc
Performance
Fast, precise and automatic to judge the sound parameters. Real-time wave display to assure test efficiency
Graphically display the test data, the user can view result directly.
Can connect with the test hammer directly to detect the concrete strength. The function has been applied for national patent.
Can receive signal with strong sensitivity more than 10m without defects in concrete.
The host can supply energy to transducer without external power.
Standard USB storage with big capacity
Interior lithium battery can supply working power more than 6 hours. And more than 12hours combined with external lithium battery.
Portable, small and light apparatus(1.75kg)
Extending function to test concrete thickness by impact-echo method
Professional and powerful analysis software on Windows system can output the data to Excel or word for advanced analysis.
