KM 1320 Earth Resistance Soil Resistivity Tester is specially
designed and manufactured for measuring earth resistance, soil
resistivity, earth voltage, AC voltage. 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, 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 host machine, monitoring software, testing wires, auxiliary
ground pillars, communication wires and others. The large LCD
display of host machine is 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 the functions like historical data
access, reading, preservation, report forms, printing and so on.
