UT572 is for measuring earth resistance and soil resistivity. It can automatically check interface connection and detect interference voltage/frequency, with data hold and indication functions. It can perform 2/3/4-wire measurements for di?erent on-site applications, such as power equipment wiring and lightning protection equipment.
The UNI-T UT572 is a professional-grade earth resistance tester designed for precise ground system evaluation and soil resistivity analysis. Engineered for electrical contractors, power system technicians, and facility maintenance professionals, this advanced instrument delivers reliable measurements for power equipment wiring, lightning protection systems, and telecommunications infrastructure. With multi-wire testing capabilities, automated connection verification, and interference detection, the UT572 ensures accurate ground resistance evaluation in diverse field conditions to maintain safety standards and electrical system integrity.
The UNI-T UT572 delivers exceptional measurement precision with dual test frequencies (94Hz and 128Hz), enabling accurate earth resistance readings even in environments with electrical interference. With measurement ranges spanning from 4Ω to 40kΩ and resolution down to 0.01Ω, it provides the detailed data necessary for comprehensive ground system evaluation. The tester automatically detects potentially disruptive interference voltage up to 50V and identifies frequencies between 40Hz-500Hz that could affect measurement integrity. The specialized soil resistivity function allows precise evaluation of ground conditions for new installations, with adjustable test distances from 1m to 40m, providing critical data for optimal grounding electrode placement. For advanced diagnostics, the UT572 includes dedicated RH and RS testing capabilities to identify individual electrode contributions to overall resistance, along with compensating resistance (RK) evaluation to account for test lead effects in high-precision measurements.
