Product Description
Application:
ETCR2000 clamp ground resistance tester is a major technological breakthrough in traditional grounding resistance measurement. It is widely used in the grounding resistance measurement of electric power telecommunications meteorology oilfield construction and industrial and electrical equipment. When measuring circuit grounding system it is not necessary to disconnect the each connection wire and use auxiliary electrode it is safe and quick easy to use. Can measure the grounding fault which can not be measured by the traditional method because this instrument measure the integrated value of grounding resistance and ground lead resistance apply to the occasion that can not use the traditional method.
Features:
◆Apply to all kinds of ground lead.(round bar flat bar angle iron).
◆Non-contact measured grounding resistance safe fast.
◆Without using assistant ground rod. Without interrupting the grounding of the device under test.
◆With double protecting insulation.
◆With strong anti-interference ability and high accuracy.
◆Use 5# alkaline batteries convenient for users.
