The meter is designed in accordance with the technical regulations of JGJ/T23-2001, used for testing concrete compressive strength within the range of 10-60Mpa. It employs a system standard energy of 2.207J and features a value-indicating system with a pointer for direct reading. Our concrete resiliometer has received approval as a "Recommended Product for Engineering Construction" by the Ministry of Construction. The manufacturing process is supervised by the Shanxi Institute of Building Research, which contributed to the composition of the "Testing Concrete Compressive Strength Technical Regulation of JGJ/T23-2001 with Springback Method."
