Products Specifications
The high strength Schmidt hammer is used to test strength of high-rise buildings structure components, bridges, and concrete components( board, beam, column, crane span structure. It's common modern building NDT equipment.
Features
The guiding rod is made of high quality imported material, with high accuracy and abrasion-proof.
Ultrasonic aluminum enclosure prolong the tooling life;
External spring structure is easy for friction adjusting and also can guarantee uniform friction force between needle pivot and slider, thus to assure the instrument accuracy.
