Overview of Sonel MRU-10 Earth Resistance Tester:
The MRU-10 is a simple earth resistance tester that allows you to measure grounding by the use of the technical method and to measure grounding resistance by the use of the 2-pole method. The instrument is easy to handle, resistive to interference, and highly accurate.MRU-10 is a basic device that allows checking the quality of the grounding system on the basis of the received measurement result. Its ergonomic shape, durable and firm housing, as well as big and clear display make this instrument ideal to use both in the field and most working environments. The device is simple to operate and intuitive.It is the best choice for electrical installations contractors, technicians, and professionals dealing with grounding measurements.
