It is in accordance with technical regulation of JGJ / T23-2001, used for testing of concrete compressive strength within the scope of 10-60Mpa, with the system standard energy of 2.207J, and value indicating system of pointer direct reading. Our concrete resiliometer has been approved as "Recommended Product for Engineering Construction" by the Ministry of Construction. Shanxi Institute of Building Research, who composed "Testing Concrete Compressive Strength Technical Regulation of JGJ / T23-2001 with Springback Method", supervises the manufacturing process.
Light (saving 2/3 forces compared with counterpart products), flexible, inexpensive, power-free, easy to master; the button applies stretching technical and is not easy to fall off; the pointer is easy to adjust friction Therefore, it is. the first choice applicable for on-the-spot NDT.
