The NELD-DTV Concrete Dynamic Modulus of Elasticity Tester developed by Beijing Nai'erde Company, incorporating advanced foreign technology, is specifically designed to measure the relative dynamic modulus of elasticity changes in concrete before and after freeze-thaw cycle tests. The product utilizes piezoelectric sensors, imported displays, and offers high testing accuracy, good repeatability, ease of operation, and scientific structure. It is a more scientific and ideal product for配套 use with freeze-thaw cycle tests. Widely used for measuring the dynamic modulus of elasticity of concrete, carbon, slate, glass, bricks, plastics, and metal materials.
