1. Measurement resolution:

• 1/500 pixels (using special materials to test special lens, 25mm field of view)

  
  

•  Displacement resolution: 0.05mm

  
  

• Strain resolution: 5 micro strains

  
  

  2. Features:

  
  

• Measurement object: a variety of materials (can be connected to the testing machine) metal, rock soil, plastic, rubber, composite material, polymer material, leather, optical fiber, film, wood, biological material, etc.;

  
  

•  Set gauge length arbitrarily (small size samples can be measured);

  
  

•  Measurement under special conditions:

  
  

•  High temperature measurement above 800 degrees;

  
  

•  Low temperature measurement of minus 100 degrees;

  
  

•  High-speed impact and high-frequency vibration;

  
  

•  Fracture, damage and destruction experiments;

  
  

•  Fatigue test: there will be no slippage of the measuring instrument, it can work for a long time, and the measurement effect is stable;

  
  

•  Micromechanics measurement: Take pictures with scanning electron microscope (SEM) and other instruments to measure micromechanics;

  
  

•  Feedback control of measuring strain signal can be realized (for example, when doing fatigue experiment, using strain signal to control fatigue testing machine).
