Description

Earth Resistance and Soil Resistivity Tester
Model: GRT-200
The GRT-200 offers a comprehensive solution to your earth resistance and soil resistivity testing needs. With an IP54 rated enclosure it is the genuinely outdoor instrument. The instrument provides all the functions required for ground system testing: earth resistance measurement by four-wire, three-wire or two-wire method, attached auxiliary ground rod, ground noise voltage measurement and soil resistivity measurement.
The clear, easy-to-read display provides excellent contrast and viewing angle making the instrument ideally suited to outdoor use. The display is backlit, extending the operational environment of the instrument to cable cellars and other dark locations.
The GRT-200 offers a wide measurement range of 0.01 Ω a to 30.00 kΩ, ground noise voltage measurement from 0.00 V to 100.0 V and Soil resistivity measurement from 0.00 Ωm to 9999 kΩm. Accurate results can be obtained in electrically noisy environments since the instrument is capable of rejecting noise voltages of 20 V peak to peak.

Main Features
1)Able to measure earth resistance by four-wire, three-wire or two-wire method
2)Able to measure soil resistivity
3)Able to measure ground voltage and AC voltage
4)Test frequency: 128Hz
5)Short circuit test current: > 20mA(sinewave)
6)4-bit large backlit display screen
7)Rugged carry case
