describe

Complies with JGJ/T294-2013 technical regulations.This product is suitable for testing the strength of high-rise building components, bridges, and concrete components (plates, beams, columns, and bridge frames). Generally applicable to C50-C100 concrete, the concrete strength should be evaluated and accepted according to the national standards "Code for Construction Quality of Concrete Structures" GB50204 and "Standard for Inspection and Evaluation of Concrete Strength" GB/T50107.

characteristic

1）The central guide rod is made of imported materials, with high precision and wear resistance;

2）The shell is made of ultra hard aluminum to avoid damage to the instrument during on-site operations and extend its service life;

3）The pointer slider adopts an external spring coil structure, which not only facilitates the adjustment of friction force, but also ensures the uniform friction force between the pointer shaft and the pointer slider, ensuring the accuracy of the instrument. Compared to peers, our products are of high quality, affordable, precise, and have a long service life.
