SONEL SA products

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. With the use of the Sonel MRU-120HD meter it is possible to perform earth resistance measurements using the 3-pole and 4-wire method. The instrument also allows measurements to be made using additional clamps (multiple earthing – without the need to disconnect the monitoring connections) and measurements using the two-clamp method. In some cases, the measurement can be done without the use of auxiliary probes driven into the ground. Sonel MRU-120HD is a tool designed especially for earthing measurements in the power industry. Measuring range (measurements in accordance with EN 61557) from 0.30 Ω.

The functional insulation resistance meter Sonel MIC-2511 allows you to measure insulation resistance with a test voltage of up to 2500 V. It surprises with numerous functions hidden in a neat and handy form. Due to its parameters, robust housing with IP65 protection level, low energy consumption from batteries and the possibility of recharging during measurements, the meter is a reliable tool that can be used in many areas. It is perfect for controlling industrial installations and traction networks, it is also successfully used in residential construction. The advantages of this device are especially appreciated by electricians working in maintenance, testing motors, cables and street lighting. The Sonel MIC-2511 meter is also useful for measurements during the construction and maintenance of photovoltaic installations. It is a reliable solution created for the needs of telecommunications network installers and heating network operators,
