GTJ-HT225W automatic wireless rebound hammer
Usage overview
The GTJ-HT225W automatic digital resilience instrument 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
