Non Contact Earth Ground Resistance Detector Online Earth Resistance Tester 200Ω
Instruction:
ETCR2800C 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.
ETCR2800C Non-contact Earth Resistance Online Detector, equipped with display screen and alarm lamp, can observe the value of earth resistance at any time , and can set alarm critical value , when the value of earth resistance is larger than the setting critical value , alarm lamp will flashes , it`s suitable for independent installation and use no need to build network. the detector equipped with GPRS communication and RS485 interface , can build a network system to realize real-time detection and remote monitoring.
