VICTOR 6412E explosion-proof clamp type grounding resistance instrument has passed the explosion-proof certification and meets the requirements of GB3836-2000 "Electrical Equipment for Explosive Gas Environment". Its explosion-proof mark is Ex ia II BT3Ga. The shell of the pliers watch is made of anti-static engineering stic, which is more safe and reliable. It can be applied to the corresponding inflammable and explosive environment
VICTOR 6412E clamp type earthing resistance instrument is widely used for earthing resistance measurement and circuit resistance measurement of electric power, telecommunication, meteorology, oil field, construction and industrial electrical equipment. When measuring the ground system with loop, it is not necessary to disconnect the ground lead line and auxiliary electrode, which is safe and fast. It can measure the ground fault that cannot be measured by the traditional method, and can be applied to the occasion that cannot be measured by the traditional method, because the clamp ground resistance meter measures the combined value of the grounding resistance and the grounding lead resistance
