Usage overview
The GTJ-HT225 fully automatic integrated rebound hammer is a non-destructive testing and evaluation instrument for compressive strength of hardened concrete in building structures. It can detect and record parameters such as rebound value, carbonization depth value, angle, test surface and so on. The strength estimation result of the member can be immediately given after the detection is completed.
Applicable standard
"Jumpback Instrument" GB9138-2015
Technical Regulations for Testing Concrete Compressive Strength by Rebound Instrument Method JGJ/T23-2011
Features
※Integrated design. Small size
※ Adopt new MOS image sensor to subvert the traditional signal acquisition method, the data is accurate and reliable
※Special color screen display, automatic record detection time and date
※The machine can match the national uniform and local curve, and you can set your own choice.
※The angle, test surface, pumping, carbonization and other parameters can be set on site.
※ Voice registration function, noisy environment can also be equipped with earphone monitoring
※ Optional micro printer on-site printing test results
※Ultra low power consumption design, continuous use of power supply time 8~10 hours
※With high-speed USB data transfer port to transfer data to computer
※The PC software saves the data in excel format, and can directly generate the word report format. It is simple and convenient for your later software processing.
