AMRU-10 Telurometer

AMRU-10 Telurometer

AMRU-10 is a simple meter that allows to perform measurements by the technical method, as well as the measurement of the resistance of the grounding by the bipolar method. The device is characterized by its ease of operation, high resistance to disturbances and high accuracy.

AMRU-10 is a simple to use meter intended for earth resistance measurements. It is a basic device that allows checking the quality of the earthing circuit from the result obtained from the measurement. Its ergonomic shape, robust and compact housing, as well as its large and readable display make this device an ideal solution for use in the field and in most working environments. The device stands out for its simple operation and intuitive handling. It is the best choice for electrical installation contractors, technicians and specialists dedicated to grounding measurements.

It allows to make measurements of:

  • Earthing resistors by the technical method (3p),
  • Resistances by the bipolar method (2p),
  • Disturbance voltages up to 100 V,
  • RH and RS auxiliary electrode resistors.

Besides:

  • Display of battery or accumulator status
  • Auto power off function
  • Choice of measuring voltage 25 V and 50 V
