The Sonel MRU-120HD earth resistance and soil resistivity meter is a robust and functional device characterised by particular resistance to difficult working conditions. It is not afraid of dust or mud and performs excellently even in areas where there is an increased risk of splashing.

Additional features

• Outstanding resistance to harsh environmental conditions – the suitcase housing protects against the ingress of dust and water and protects against the effects of falls
  
• Measurement of resistance of auxiliary electrodes RS and RH
  
• Measurement of interference voltage
  
• Measurement in the presence of interference voltage generated by power networks with frequency of 50 Hz or 60 Hz
  
• Selection of maximum measuring voltage (25 V and 50 V)
  
• Automatic calculation of soil resistivity in ohm-meters (Ωm) and ohm-feet (Ωft)
  
• Memory of 990 measurement results (10 banks of 99 cells each)
  
• Calibration of clamp used
  
• Real time clock (RTC)
  
• Data transmission to the computer
  
• Battery indication

MRU-120HD provides valuable data for accurate assessments, making it a preferred choice for professionals seeking reliable performance in challenging conditions.
