Product Introduction
ETCR EM2000B+ Explosion Proof Clamp Earth Resistance Tester, also known as explosion proof earth resistance tester and explosion proof clamp type earth resistance tester, which is used for measurement of earth resistance, loop resistance, and grounding fault judgment.
In the loop grounding system measurement, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is safe, fast and convenient to use.the clamp earth resistance tester is widely used in earth resistance and loop resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.The long clamp is particularly suitable for flat steel grounding site.
The tester can measure ground faults that cannot be measured by traditional methods, and can apply to the site which cannot be measured by traditional methods, because the clamp earth resistance tester is measuring the comprehensive value of the grounding body resistance and the grounding lead resistance.
ETCR EM2000B+ Explosion Proof Clamp Earth Resistance Tester has passed explosion proof certification and meets the requirements of GB/T 3836.1-2021 and GB/T 3836.4-2021.Its explosion-proof mark is ExiaⅡBT3Ga.Explosion-proof certificate number: CE23.3879. It can be applied to the corresponding flammable and explosive environment.
1.Non-contact measurement is safe and fast. When measuring the loop grounding system, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is saving time and efficient.
2.The clamp earth resistance tester can measure ground faults that cannot be measured by traditional methods, and can apply to the site which cannot be measured by traditional methods.
3.With data hold function, storage function, alarm function.
4.ETCR EM2000B+ Explosion Proof Clamp Earth Resistance Tester can be used in the corresponding environment, and the shell is made of anti-static engineering plastics, which is safer.
5.Explosion-proof mark: ExiaⅡBT3Ga, Explosion-proof certificate number: CE23.3879.
