简要描述: 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

产品介绍

Specification

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

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.
