APPLICATION :
The Concrete Tester Hammer RH20-A uses a spring to drive the bounce hammer, and through the bouncing rod, the restoring force of the instantaneous elastic sdeformation generated by the surface of the masonry mortar makes the hammer drive the pointer to bounce back and indicate the rebound distance. This rebound value is used as one of the relevant indicators for evaluating the compressive strength of mortar to estimate the compressive strength of masonry mortar in sintered ordinary bricks or sintered porous brick masonry.
PRODUCT FEATURES:
The spring of the whole machine is made of imported high-quality steel wire, the material of the core steel is excellent, and the current exquisite processing technology is used, so the rebound value is more stable;
The pointer direct-reading mortar hammer has a clear scale and is easy to use;
Low-load grating and optocoupler sensor ensure stable and accurate sampling of the digital hammer;
