HT-20 Mortar rebound testerDetailed product description：

The HT-20 mortar rebound tester is a spring driven hammer that uses the restoring force of instantaneous elastic deformation generated by the hammer hitting the surface of the brick sample through the hammer rod. The hammer drives the pointer to rebound and indicates the rebound distance. The rebound value is used as one of the relevant indicators to evaluate the compressive strength of mortar, and to estimate the compressive strength and grade of mortar. It is used for nothing
An instrument for detecting the compressive strength of masonry mortar in sintered ordinary brick masonry of industrial and civil general buildings.
