Electronic grounding resistance tester DY2571S

Product introduction

DY2571S grounding resistance tester is specially designed and manufactured for on-site 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 is up to 20mA. Digital and micro processing technology, precision 4-wire method, 3-wire method and simple 2-wire method are used to measure the grounding resistance. FFT (Fast Fourier Transform) technology and AFC (Automatic Frequency Control) technology are introduced, Automatically identify interference and select measurement frequency to minimize the impact of interference and provide more accurate grounding resistance value. It has unique anti-interference ability and environmental adaptability, good consistency of repeated tests, and ensures high accuracy, stability and reliability of long-term measurement. It is widely used in the measurement of grounding resistance, soil resistivity, grounding voltage and AC voltage of electric power, telecommunications, meteorology, oil fields, buildings, lightning protection and industrial electrical equipment.

DY2571S grounding resistance tester, also known as precision grounding resistance tester, four wire grounding resistance tester, two three four wire grounding resistance tester, and grounding resistance tester, is composed of host, data software, test wire, auxiliary grounding rod, communication wire, etc. The main engine is designed as a special toolbox, using polypropylene plastic as the raw material and adding new composite fillers for one-time injection molding. It has low density, strength, stiffness, hardness, wear resistance, heat resistance and insulation performance. Its box can withstand a pressure of about 200kg, ensuring high accuracy, stability and reliability of various environmental tests. The mainframe has a large LCD display with backlight and bar graph indication, which is clear at a glance. At the same time, 2000 groups of data can be stored, and historical data reading, viewing, saving, reporting, printing and other functions can be realized through data software.
