Product overview ：

For a certain object, there is an inherent worry resonance frequency. When the volume or material of the object is fixed, the resonant frequency of the object is only equal to its density. Therefore, the natural vibration frequency of the object determines its strength. If the resonance frequency of the object can be measured, the strength of the object can be calculated according to the strength theory. The dynamic elastic instrument is an instrument that uses the above principle to measure the resonance frequency of the object. It can be widely used in metallurgy, construction, bridge, hydropower and other fields to measure the dynamic elastic modulus of concrete, carbon, slate, glass, brick, plastic and metal materials.

Product features ：

1. The frequency sensitivity of manual measurement is up to 1Hz. Frequency hopping scanning can be implemented from 100Hz to 20kHz (i.e. coarse scanning with tens of hundreds, thousands or tens of thousands bits), and fine scanning (fine scanning with precise digits after coarse scanning to the value, until accurate to 1Hz).

2. With memory, it can store 100 test data, export data and print data in a centralized way.

3. All Chinese LCD display can display the current scanning frequency, resonance peak frequency and signal strength in real time. Compared with other manufacturers' oscilloscope tube display, it has the advantages of intuitive, high accuracy and convenient reading.
