Grounding resistance tester
KD2571 ground resistance tester is suitable for electric power, posta si telecomunicatii, railway, petroleum, chimic, comunicare, mining and other departments to measure the ground resistance of various devices and measure the conductor resistance value of low resistance, this table can also measure the soil resistivity and ground voltage.
Grounding resistance tester
Product characteristics
Compared with the traditional hand-operated earth resistance meter, this instrument has the following characteristics:
1, the application of DC/AC conversion technology, set three-end button, four-end button as one, the use of power can be AC, DC dual use.
2, the use of phase-locked synchronous tracking detection mode, and switched capacitor filter, so that anti-interference ability is strong.
3, abandon the traditional manual hand-operated power generation mode, do not need human work.
4, no manual adjustment balance, clear panel touch key operation, LCD digital display makes the measurement is very convenient and rapid, eliminating the visual error of the pointer instrument.
5, the allowed auxiliary grounding resistance resistance value is very large, better ensure the measurement accuracy, Rezoluție înaltă.
6. In addition to testing the grounding resistance, it can also test the electrical group value of the low-voltage resistance conductor. Soil electrical composition and alternating voltage.
