earth resistance tester

The RD3000B ground resistance tester is designed and manufactured specifically for the on-site measurement of ground resistance, soil resistivity, ground voltage, and AC voltage in combination with the new lightning protection ground resistance test 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. Introduced 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 grounding resistance. Our Earth Resistance Tester has unique anti-interference ability and environmental adaptability, and it has good consistency in repeated tests to ensure high accuracy, high stability and high reliability of long-term measurement. The ground resistance meter is widely used in power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, such as ground resistance, soil resistivity, ground voltage, AC voltage measurement
