the S480 earth resistance and soil resistivity tester is specially designed and manufactured for ground resistance, soil resistivity, ground voltage, AC and AC voltage in combination with the new lightning-proof ground resistance testing standard. the testing current reaches 20mA. the digital and micro-processing technology, precision 4-wire method, 3-wire method and simple 2-wire method are used to measure ground resistance, importing FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, with a unique function of anti-interference capability and the ability to adapt to the environment, consistency of repeat testing, to ensure high precision, high stability and reliability for prolonged measure, which is widely used in electric power, telecommunications, meteorology, oil field, construction, lightning protection, industrial electrical equipment and other earth resistance, soil resistivity, earth voltage, AC voltage measurement

 

S480 Earth ResistanceSoilREsistivity Tester also named: Precise Earth Resistance Tester, 4-pole Earth Resistance Tester, 2/3/4-pole Earth Resistance Tester, SoilREsistivity Tester, the S480 earth resistance and soil resistivity tester is composed of host machine, data software, test line, auxiliary grounding rod, communication line and so on. the special toolbox design of the main engine uses polypropylene plastics as raw materials and adds a new type of composite filler for one-time injection molding. It has the advantages of low density, strength, stiffness, hardness, abrasion resistance, heat resistance and insulation. the box can withstand about 200 kg of pressure to ensure high precision, high stability and high practicability of various environmental tests. the host of large LCD display with backlight, bar graph indicating that can be seen clearly, it can store 2000 sets of data. through data software, it can realize the functions of reading, consulting, saving, reporting and printing historical data.
