Product use
CHT225-A concrete strength Tester, test concrete strength is a comprehensive instrument. Can be used as a normal rebound instrument, and can be used as a comprehensive method of ultrasonic and rebound detector, which can measure the rebound value and when measuring the sound, sound. Suitable for all kinds of building works in the common non-destructive testing of concrete compressive strength.

Standard specification for
Rebound test: national industry standards: the rebound hammer technical specification for inspection of concrete compressive strength (JGJ/T23-2011).
Ultrasonic-rebound combined method: construction industry-standard technical specification for the comprehensive method of ultrasonic and rebound strength (CECS, 02:2005).

Technical characteristics
1. concrete strength testing instrument. Can use the rebound method and ultrasonic-rebound method method of test for compressive strength of concrete.
2. implemented a comprehensive method of ultrasonic and rebound test. One instrument to achieve a comprehensive method of ultrasonic and rebound test can be measured the value of rebound and when measuring the sound, sound, simple and convenient.
3. the test spot to get test results. After the test is completed, according to the test data can be obtained directly by rebound method and ultrasonic-rebound combined method of test results.
4. the instrument to set the test date. Data save the test date, user-friendly data management.
5. real USB data transfer. Pass test data into the computer for further analysis.
6. ultrasonic and rebound device using infrared communication, eliminating the drag of the signal wire.
7. powerful professional Windows data analysis and processing software. Test results expressed in graphics, you can directly generate the Word test reports or import the data into Excel, quick and easy.
