It is used to detect the strength of high-rise building components, bridges and such components (plate, beam, column, bridge). The concrete which is usually suitable for c50-c100 should be accepted and evaluated according to the national standard "code for construction quality of concrete structures" GB 50204 and "standard for inspection and evaluation of concrete strength" GB / t50107.
characteristic:
1) The center guide rod is made of material with high precision;
2) The shell is made of duralumin;
3) The pointer slider adopts an external spring coil structure, which is convenient for friction adjustment, and the friction between the pointer shaft and the pointer slider is uniform.
