产品介绍
Application: used to test compressive strength of concrete by two ways: rebound and ultrasonic-rebound method. Also, it can be used to test sound time and wave speed in concrete.
Standard:
JGJ/T23-2011 Technical specification for inspection of concrete compressive strength by rebound method
CECS02:2005 Technical specification for detecting strength of concrete by ultrasonic-rebound combine method
Features:
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.
3. Can save test date. This is convenient for data management.
4. USB data transmission. Data can be transmitted to computer for future processing and analysis.
5. Powerful data process and analysis software, test data can be exported to word or excel for future process and analysis.
