Earth/Ground Resistance Online Detector/Tester ( MiniType,Wired system)

https://www.sltup.com/Earth-Resistance-Online-Detector-Factory-Price-China-Supplier-Minitype-Wired.html

Earth Resistance Online Detector developed by Sunlight company does not change any design structure of the original grounding system, and adopts on-line monitoring technology such as non-contact measurement, which will not affect the grounding effect and the normal operation of facilities. There is no need for self-test and real-time detection,and The product can be installed and used as a single product, or it can be formed into a wired network system or a wireless network component system. With the support of the system, the data can be stored. Through the curve display of the accumulated data, you can intuitively see the changing trend of the ground grid and detect whether the ground grid is in health conditions or not.

Earth Resistance Online Detector (Mini Type, wired) transmission modes

Wired network system: data transmission through RS485 communication protocol, composed of main communicator (concentrator), monitoring software, power adapter, computer, etc., suitable for close distance, convenient construction wiring.

Sunlight Earth/Ground Resistance Online Detector/tester advantages(Mini Type, wired mode) 

Sunlight grounding resistance online monitoring system passes various tests, such as The highest harsh level requirements stipulated by surge, static electricity, pulse group, radiation immunity, power frequency magnetic field immunity, voltage short drop, radio frequency magnetic field conduction harassment, That is  to say, Sunlight Earth/Ground Resistance Online Detector/tester (Explosion proof) can work in a stable strong interference environment. 

also, the product passes the 100 KA lightning surge test. That is to say,  during the actual operation of the product, when 100 KA lightning current pass through, Sunlight Earth/Ground Resistance Online Detector/tester detector works normally.
