Non Contact Grounding Resistance Online Detector Online Tester

Description

Non Contact Grounding Resistance Online Detector Online Tester
Introduction
ETCR2800B Non-Contact Grounding resistance Online Detector used for on-line monitoring the earthing resistance of earthing system, measure range: 0.010Ω~200Ω. 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 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.
ETCR2800B 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.
