ZK-BC880 Pendulum Knockin Instrument

Application Industry

ZK-BC880 Pendulum Knockin Instrument is a new type of testing instrument that uses a fixed force value to knock the measuring nail into the tested component, and estimates the compressive strength of the component material by measuring the tapping scale of the measuring nail. Suitable for on-site testing of compressive strength of bricks and masonry mortar in sintered ordinary brick masonry engineering, on-site testing of compressive strength of autoclaved aerated concrete blocks and masonry mortar in masonry engineering, on-site testing of compressive strength of ordinary concrete, and on-site non-destructive testing of chordwise static bending strength of wood in engineering structures

Features

Easy to operate, no need for power drive, accurate detection;

By using fixed potential energy to knock in detection, human error can be avoided and detection accuracy can be improved

By replacing the measuring pins, it can be used for strength testing of different materials

Testing data processing and analysis software, easy to complete data processing and report generation
