1、Multi-function for testing compressive strength of concrete. It is used to test the compressive strength of concrete by rebound method and ultrasonic-rebound method.

2、Get the compressive strength value of concrete by ultrasonic-rebound method in one instrument. it need two instrument usually, one to test sound speed in concrete, the other to test rebound value.

3、Can save test date. This is convenient for laborer data management.

4、Real USB transmission. Data can be transmit to computer for future process and analysis.

5、Powerful data process and analysis software in windows. Test data can be export to word or excel for future process and analysis.
