This product is suitable for testing 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 standard of 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 imported material, with high precision and wear resistance;
2) The shell is made of super hard aluminum to avoid damage to the instrument during field operation and prolong its service life;
3) The pointer slider adopts the external spring coil structure, which is not only convenient for friction adjustment, but also can ensure the uniform friction between the pointer shaft and the pointer slider, and ensure the accuracy of the instrument. Relative to peer products, high reliability, long service life.
