    Product Description

    GDCR3000B Earth Resistance/Soil Resistivity Tester is special designed for measuring earth resistance, soil resistivity, earth voltage and AC voltage. The latest digital and micro processing technology is adopted, to measure earth resistance by 4-pole, 3-pole or 2-pole. FFT(Fourier transform) technology, AFC(automatic frequency control) technology is also available, with good anti-interference ability and the ability to adapt to the environment, to ensure high precision, high stability and reliability.

    It’s widely used for measurement of electric power, telecommunications, meteorology, oil field, construction, lightning protection, industrial electrical equipment.
