UNI T 4 Pole Soil Resistance Earth Tester Meter UT523A is specially designed and manufactured for measuring earth resistance, soil resistivity, earth voltage, AC voltage.UT-523A earth resistance meter, adopting the latest digital and micro-processing technology, precise 4-pole, 3-pole, and simple 2-pole method for earth resistance measurement, importing FFT and AFC technology. This earth resistivity meter with a unique function of anti-interference capability and the ability to adapt to the environment, consistency of repeat testing, to ensure high precision, high stability and reliability for the prolonged measure. This ground resistance meter is widely used in electric power, telecommunications, meteorology, oil field, construction, lightning protection, industrial electrical equipment and other earth resistance, soil resistivity, earth voltage, AC voltage measurement.

Features Of UNI-T UT523A Earth Resistance Voltage Soil Resistivity Tester Meter:

  • UT523A intelligent earth resistance tester is designed to measure earth resistance, soil resistivity, earth voltage, and AC voltage.
  • It used accurate 4-pole, 3-pole, and simple 2-pole methods to measure earth resistance.
  • Fast Fourier Transform(FFT) and Auto frequency control(AFC) are integrated into this tester.
  • So it has unique anti-interference capability and also is more reliable.
