I. Brief Introduction ETCR2000BNon-Contact Resistance Online Tester is our company devotes ourselves to Grounding resistance test technical research’s another new high-tech product for more than ten years. Detector adopts weather fastness material manufacture, temperature resistance, cold-resistant, corrosion prevention, fire prevention. Detector’s structure is rigorous and firm, against rain, dustproof, installation and use outdoors. Non-contact measurement, safe and reliable, Ease of installation. Grounding down lead is directly through the detector perforation, Will not affect lightning protection grounding effect and the normal operation of the facilities. Ensure high-accuracy, high stability and high reliability of long time on-line monitoring outdoors, underground mine and indoors. ETCR2000BNon-Contact Grounding Resistance Online Detector applies to electric transmission line pole ground connection, underground mine device ground connection, Meteorological lightning protection ground connection, petrochemical engineering ground connection, communication ground connection, rail facility ground connection, building the warehouse ground connection, electrical equipment ground connection etc.. Detector provides power supply and RS485 signal interface, and standard MODBUS-RTU communication protocol,which user can do secondary development to realize remote monitoring. II.
