20mA Strong Anti-Interference Ability Digital Grounding Resistance Tester

 

 

Product introduction

 

The ZXET3005 Digital Grounding Resistance Tester is designed and manufactured according to the new lightning protection grounding resistance detection standard. The short-circuit test current reaches 20mA. The precision 3-wire method or simple 2-wire method measures the grounding resistance. The FFT (fast Fourier transform) technology is introduced, AFC (Automatic Frequency Control) technology has unique anti-interference ability and environmental adaptability, and the consistency of repeated testing is strong. It is widely used in the measurement of grounding resistance and grounding voltage in electric power, telecommunications, meteorology, oil fields, construction, lightning protection, and industrial electrical equipment.
