China Large-Scale Grounding Grid Earth Resistance Tester

Product Description:
HZDW-603 Earth Grounding resistance tester uses new type variable frequency AC power supply and the measures of microcomputer process control and signal processing and so on, well solved the anti interference problem in test process. This device applies to test power frequency groud resistance, contact voltage, pace voltage and earth resistivity.
Product Features:
1.Good equivalence of power frequency measurement.
2.Strong anti-interference ability. This instrument adopts different frequency measurement method, combined with modern hardware and software filtering technology.
3.High precision. Basic error is only 0.005Ω, can be used to measure the small grounding impedance of ground network.
4.Powerful function, can measure current station, grounding resistance, pace voltage, contact voltage.
5.Small wiring labor, no large current line.
