Earth Resistance On-Line Tester
SGT-10B Earth Resistance On-Line Tester
SGT-10B earth resistance on-line tester is a new-type digital and
precise earth resistance on-line tester developed by our company.
It is widely used in the fields of resistance testing for earth
resistance of telecommunication, power system, buildings, military
facilities and towers etc. it not only can test the earth
resistance with the measurement method of 2, 3, 4 wires, but can
test the alternative voltage and soil resistivity. It is a product
with advanced design and easy for operation.
Key Features:
No assistant poles when adopting the measurement method of 2-wires.
Easy and convenient operation
With the function of testing under the condition of on-line and
off-line, with the function of data storing;
Small structure and the compact characters, which can meet the
demands of the operation under the condition of harsh-environment;
Eliminate the resistance of testing line by adopting the
measurement method of 2, 3 wires.
Test the earth resistance and soil resistivity adopting the
measurement method of 3, 4 wires, which can test the alternative
voltage.
Automatic test, stop testing in the case of misoperation;
intelligent measurement which can guarantee the safety of
operation;
