Earth Insulation Tester
Double Clamp Grounding / Earth Resistance And Soil Resistivity Tester
The ZXET3007 grounding resistance tester is designed and manufactured for field measurement of grounding resistance, soil resistivity, grounding voltage, and AC voltage in combination with the new lightning protection grounding resistance detection standard.
The test current reaches 20mA, using digital and micro-processing technology. Precise 4-wire method, 3-wire method and simple 2-wire method for measuring ground resistance, introducing FFT (Fast Fourier Transform) technology and AFC (Automatic Frequency Control) technology to automatically identify interference and select the measurement frequency to minimize the impact of interference, provide more accurate ground resistance value.
