Sonel MIC-2511 Insulation Resistance Meter

Sonel MIC-2511 Insulation Resistance Meter

SKU: MIC-2511

The Sonel MIC-2511 Insulation Resistance Meter measures insulation resistance up to 2 TΩ using a test voltage of up to 2500 V. With its compact design and robust casing (IP65 protection), this meter offers various functions while conserving battery power. It’s versatile for industrial installations, catenary networks, residential buildings, motor, cable, and street lighting testing. It’s also valuable in photovoltaic installation maintenance, telecommunications, and heating network management, aiding in pre-insulated pipe alarm system control.


  • Measurement voltage range of 10 to 2500 V, selectable in increments of 10 V.
  • Insulation resistance measurements for fire alarm system supervisory loops at 10 V.
  • Charts displayed during measurements.
  • Suitable for Electrostatic Protected Areas (EPA).
  • Correction of insulation resistance results to reference temperature.
  • Continuous reading of insulation resistance or leakage current.
  • Automatic discharge of object capacitance after measurement.
  • Sound alerts in five-second intervals for time tracking.
