Introduction
Soil Resistivity Tester also Known as Ground Resistance • Soil
Resistivity Tester, Precision Ground Resistance Tester, etc., is a commonly
used meter for measuring grounding resistance. It adopts a large LCD
gray-white screen backlight display and microprocessor technology to meet
the requirements of two-wire
、 three-wire and four-wire test resistance and
soil resistivity. Suitable for telecommunications, electricity, meteorology,
computer rooms, oil fields, power distribution lines, iron tower
transmission lines, gas stations, factory grounding networks, lightning rods
and so on. Instrument testing is precise, fast, simple, stable and reliable.
The Soil Resistivity Tester is controlled by the microprocessor and can
automatically detect the connection status of each interface and the
interference voltage and interference frequency of the ground network, and
has the function of testing the auxiliary grounding resistance value. At the
same time store 500 sets of data,
resistance measurement range: 0.01 Ω ~
30.00k Ω , grounding voltage range: 0.01 ~ 100.0V. Online monitoring data
through monitoring software, USB data uploaded to PC and unique features such
as
intelligent alarm alert
The Soil Resistivity Tester c onsists of host, monitoring software, test
line, USB cable, and grounding rod. It has the functions of reading, checking,
saving, reporting and printing of historical data.
