KM 1320 Earth Resistance Soil Resistivity Tester is specially designed and manufactured for measuring earth resistance, soil resistivity, earth voltage and AC voltage. Adopting the latest digital and micro-processing technology, precise 4-pole, 3-pole and simple 2-pole methods for earth resistance measurement importing FFT and AFC technology, 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 prolonged measure, which 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.

KM 1320 Earth Resistance Soil Resistivity Tester is composed of a host machine, monitoring software, testing wires, auxiliary ground pillars, communication wires and others. The large LCD display of the host machine has with blue backlight & bar graph indicating that can be seen clearly. At the same time, it can store 300 sets of data, fulfilling historical inquiry and online real-time monitoring through monitoring software, dynamic display, alarm indicator, and with functions like historical data access, reading, preservation, report forms, printing and so on.
