Langrui Concrete Dynamic Modulus Tester DT-20 Type

1、 Overview of DT-20 Concrete Dynamic Modulus Tester
All objects have a resonant frequency. When the volume and material of an object are constant, the resonant frequency of the object is only related to its density. And the strength of an object is related to its density, so the natural frequency of an object determines its strength. If we can obtain the resonant frequency of an object through some means, we can calculate its elastic modulus based on its mass, volume, and resonant frequency. The dynamic energy analyzer is an instrument that uses the principle of resonance to determine the elastic modulus of a specimen. It can test the degree of internal damage or destruction of the specimen after rapid freeze-thaw or other erosion. Dynamometers are widely used in metallurgy, construction, bridges, hydropower and other fields to measure the elastic modulus of concrete, carbon, slate, glass, brick, plastic and metal materials.
The DT-20 dynamic analyzer is an instrument used to measure the elastic modulus of concrete and carbon. It uses microcontrollers and integrated circuits to process data, achieving full automation of measurement and calculation.
