Product Interview:

Earth resistance system online monitoring, metal loop connection resistance online monitoring, grounding state monitoring.

 

 

Main Features:

1. Non-contact type measurement technology, safe and reliable, easy to install. The grounding down leads passe through the tester perforation directly, will not influence the lightning protection grounding effect and device normal working.
2. The C type product is equipped with LCD screen that can be installed and used independently, and the earth resistance value can be observed at any time.
3. Equipped with RS485 interface (Support MODBUS-RTU communication protocol) or GPRS communication, connect with the computer to realize remote real-time monitoring.
4. Explosion-proof type detector can be used in the flammable and explosive environment, explosion-proof mark: Ex ia II BT3Ga, explosion-proof certification:CE18.2332X.
