SGT-12B Double-Jaws Type Earth Resistance Tester

SGT-12B double-jaws type earth resistance tester is widely used in the fields of resistance testing for earth resistance of various equipments and buildings such as telecommunication equipments, telecommunication cable, machine room, distribution lines, transmission lines of electric towers, filling stations, earth nets of factory, lighting rods and etc. it also can test the soil resistivity and leakage current of earth systems under different conditions.
It not only possesses the function of the traditional method but the features of earth resistance testing without assistant poles, beyond the limitation of principle and ways of traditional method. It realizes the on-line measurement of earth resistance without assistance poles and isolation of earth devices and equipments by adopting the principle of 2-poles measurement and the technology of double jaws.
It possesses the function of intelligent test; this tester, not only can do the work of self-checking, but also save and browse the test result, it also can upload the data and do the data analysis on PC.
Key Features:
1. Adopt the measurement method in the type of jaw and meters, can be operated without assistance poles, which can meet the demands of the operation under various condition of environment.
2. Realize the on-line measurement; it is unnecessary to isolate the earth device from equipment.
3. With advanced technology and the function of intelligent test
4. Test the RMS of leakage current under the conditions of earth/unearth of system.
5. With the function of self-checking and avoid the influence for the test result by connecting the resistance and line resistance
6. With high-accuracy and less error, resolve the problem of accuracy of small resistance.
7. Realize the alternation of functions, adopt the digital switch to cutover the function in order to improve the reliability of system.
8. Communicate with the upper-level PC to realize uploading of the test data which can be saved and printed easily.
9. Easy and convenient operation with broad range of usage and measurement, with the backlighting system.
10. With Plastic sheath and good property of anti-vibration
