Clamp On Earth Resistance Tester is widely applied in ground resistance measurement, loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment, etc. When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, which means safer and faster. Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable; Clamp Earth Resistance Tester measures the integrated value of ground resistance and resistance lead.

The formation of fluoride crystal mica is a sub-grade, and does not adsorb impurities. It was selected by the Chinese Academy of Sciences Environmental Biology Research Center Peking University, Tsinghua University, Shanghai Fudan University, Nanjing University, and more than 100 national research institutions and universities for Afm Substrate After (microscopy carrier wave), the relevant person said: Compared to natural mica, fluorite mica has better flatness and less adsorption impurities. The images observed in the analysis of the DNA structure, especially in the 1 nm to 100 nm scale, have observed surface interference fringes not found in the natural mica experiment, which are clearly dozens of times better than the natural mica Substrate. Experts involved in the experiment believe that the use of fluoride mica instead of natural mica as a substrate material is expected to catch up with the international level.
