HT-225Q Digital concrete hammer is a high-tech product, especially designed for the needs of in place test for concrete compressive strength applied to non-destructive test (ndt) hardened concrete compressive strength component in construct project
*Submit to< Technical Specification of Inspecting concrete compressive strength by rebound method> (JGJ/T23-2011.) And ASTM C805, EN 12504
* Automatic recording function improves the efficiency of measurement.
* Using sensitive operation touch keys. The keys are not easy to aging.
* Integrated wireless structure of the test hammer host and the displayer part. Easy to carry and make work efficient.
* The instrument is powered by a built-in rechargeable lithium battery, which can operate continuously for more than 10 hours
