Project Description
Product Features:
The double clamp multifunctional grounding resistance tester is combined with the new lightning protection grounding resistance test standard. It is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, ground voltage, ground wire leakage current, AC current, and DC resistance.
Using the latest digital processing technology, precision 4-wire method, 3-wire method and simple 2-wire method, selection method, double clamp method to measure grounding resistance, large-diameter current clamp design, can measure the grounding system using large grounding down conductors.
It is widely used in the measurement of ground resistance, soil resistivity, ground voltage, AC current, and leakage current in electric power, telecommunications, meteorology, oil fields, etc.
Double-clamp multi-function ground resistance tester, also known as double-clamp ground resistance tester, it also belongs to ground resistance tester,double-clamp ground resistance tester, consists of a host, current clamp (double clamp), data software, test line, auxiliary ground rod, communication line, etc. The special toolbox design of the main machine uses polypropylene plastic as the raw material, and the new composite filler is added for one-time injection molding. The density, strength, rigidity, hardness, abrasion resistance, heat resistance, and insulation performance are superior, and the box can withstand The pressure of about 200kg ensures the high precision, high stability and high reliability of various environmental tests.
The host’s large LCD display, with backlight and bar graph indication, is clear at a glance. At the same time, it can store 2000 sets of data, and the historical data can be read, viewed, saved, report, printed and other functions can be realized through the data software.
