Product Description

STDT-12 Concrete Dynamic Elastic Modulus Tester

 
Application: 
For a certain object, there is an inherent resonant frequency. When the volume and material of an object are constant, the resonant frequency of the object is only related to its density. The strength of an object is related to its density, so the natural vibration frequency of the object determines the strength of the object. If the resonant frequency of the object can be measured, the strength of the object can be derived from the strength theory. 
The dynamic tester is an instrument for measuring the resonant frequency of an object.
 It is widely used in the measurement of elastic modulus of concrete, carbon, slate, glass, brick, plastic, and metal materials in the fields of metallurgy, construction, bridges, and hydropower.

Features:
1. Single chip microcomputer and integrated circuit design and processing data are adopted to realize the whole process automation.
2. Equipped with RS230 communication port, with special analysis software, can collect the internal line of frequency and amplitude, and calculate the frequency elastic modulus accurately.
3. Equipped with special instrument , able to collect and analyze 
4. The digital potentiometer is used to increase the output frequency of the manual measurement frequency to make the measurement process more simple and accurate.
