Technical Specifications

Working Principle

The MR100 operates using a needle scanning method. As the probe glides across the surface, it detects fine texture deviations through vertical displacements of the stylus tip. These movements are translated into electrical signals by a piezoelectric wafer, then amplified and digitized by the built-in DSP processor. The device calculates roughness parameters and displays results instantly on the OLED screen.

Usage Conditions

• Operating Temperature: 0°C to 40°C
  
  

• Storage Temperature: -20°C to 60°C
  
  

• Relative Humidity: <80% (operation), <90% (storage)
  
  

• Environment: Avoid vibration, dust, moisture, and corrosive gases
  
  

Safety & Maintenance Notes

• Handle the probe carefully; always close the sensor protection door after use.
  
  

• Do not operate the device during charging.
  
  

• Recharge for about 3 hours; avoid overcharging to extend battery life.
  
  

• Keep away from strong magnetic fields, heavy dust, and moisture.
  
  

• Turn off the device after use to conserve battery.
