• The detector has strong structure, rain and dust proof, and can be installed outdoors.
• Ensure the high stability and reliability of outdoor, mine and indoor on-line inspection for a long time.
• The Non-Contact Grounding resistance Online Detector, equipped with GPRS communication and RS485 interface, can build a network system to realize real-time detection and remote monitoring.
• The detector adopts non-contact measurement technology, and the grounding down lead goes through the perforation of the detector directly, which will not affect the lightning protection grounding effect and the normal operation of the facilities.
• The Non-Contact Grounding Resistance Online Detector applies to electric transmission line pole ground connection, underground mine device ground connection, Meteorological protection ground connection, petrochemical engineering ground connection, communication ground connection, rail facility ground connection, building the warehouse ground connection, electrical equipment ground connection etc.
