Nickname: Earth Resistance Tester; ground resistance tester
Features
1、Double clamp method/ground pile method: suitable for any grounding site, multi-point or single-point grounding, can be normally tested
2、Strong anti-interference ability: generate high frequency current to filter 50Hz, 100Hz and other harmonic interference current in the commercial power supply. Even in the environment of 500kV substation, accurate measurement can be achieved
3、Dual-clamp multi-function grounding resistance tester has a wide measuring range and high resolution: the measuring range ranges from 0.01Ω~ 200 & Omega; , resolution 0.01ΩFor 0.7 & Omega; The following ground resistance can also be accurately measured.
4、Large jaw design: the diameter of jaw is 50mm(standard configuration), which can meet the requirement of using flat iron/steel as grounding lead. Special tong size can be customized according to customer requirements
5、Large-capacity data storage: 200 sets of measurement data can be stored
6、Simple operation, single operation: Chinese operation interface, small size, light weight, explosion-proof portable box, easy to carry field measurement
