UNI-T UT572 Earth Resistance Tester

UNI-T UT572 Earth Resistance Tester
This product comes with a 3-year warranty.UT572 is an intelligent device for measuring earth resistance and soil resistivity (specific earth resistance). The device is widely used in the design and testing of grounding systems for new electrical installations and lightning arresters in construction, industry, substations, telecommunications, etc.(ρ), voltage and frequency of the interfering induced signals Ust and Fst.

The device is designed with a new look with a large backlit multifunction display. It features a durable double insulated and reinforced cover.
