GTJ-HT225 automatic integrated rebound hammer
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 date 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.
