Earth Grid Grounding Resistance Tester SET-187
Strong anti-interference ability
Classification：
Power system grounding test instrument
Product description
This instrument is suitable for testing power frequency characteristic parameters such as power frequency grounding impedance, grounding resistance, auxiliary machine and soil resistivity of various grounding devices.
performance characteristics
adopts automatic double-sided advanced frequency conversion technology, measuring with 45Hz and 55Hz frequencies, and there are multiple sets of frequency conversion for selection.
• Strong anti-interference ability. Using automatic frequency conversion method, with modern hardware and software filtering technology, the instrument has a high anti-interference performance, the test data is stable and reliable.
• High accuracy. The basic error is only 0.005Ω, which can be used to measure the large ground network with small ground impedance.
clear large liquid crystal display, easy to operate
storage using keyboard Chinese character input, easy to query
