Description
UNI-T UT572 Earth Resistance Tester
This product comes with a 3-year warranty. The UT572 is a smart device for measuring earth resistance and soil resistivity (specific earth resistance). The device is widely used in the design and testing of earthing systems for new electrical installations and lightning protection in construction, industry, substations, telecommunications, etc. (ρ), voltage and frequency of induced interference signals Ust and Fst.
The device features a new design with a large, backlit multifunctional display. It has a durable, double-insulated and reinforced casing.
This device has been designed, manufactured and tested in accordance with safety standards IEC 61010 (Safety requirements for electrical equipment) in the CAT III 300 V overvoltage category, EN 61010-2-033, EN 61010-2-033, EN 61010-031, EN 61010-031.
