DTM- II Dynamic Elastic Modulus of Damping Internal Friction Analysis Instrument (Resonance)

Main technical parameters:

1. Resonance frequency:

the frequency measurement:
Frequency range: 200HZ-5KHZ, 100HZ-20KHZ.                                                   Measurement accuracy <0.5%                                                                             Frequency resolution: 1Hz
2. Dynamic elastic modulus measurements:
   Measurement Range: elastic modulus corresponding with the frequency  

   Resolution: 0.05 GPa
   Accuracy: 0.1 GPa  can measure other  peak frequency modulus quickly  

3. Damping or internal friction :10-5 --- 0.1;

4. System relative error <± 0.15%;
5. Test temperature: room temperature (or high temperature: the maximum temperature :1750 oC);

6. Can measure shear modulus;
7. Can measure poisson's ratio;

8. According to user requirements , we can provide a computer interface. It has a data storage function, display method, resonant frequency display, elastic modulus display, spectroscopy and internal friction damping display;
9. Different test samples have different test table.
