Product Introduction

ZC3-A Concrete Rebound Hammer is used to test the concrete comprehensive strength within the range of

10~60Mpa. It consists of a spring-loaded steel hammer that when released strikes a steel plunger in contact with the concrete surface.

The rebound number can be directly read on a linear scale.
