Grounding resistance online detector

Product features

Online monitoring of grounding resistance, metal circuit connection resistance, and grounding condition.

Product Features

1. Non contact measurement technology, safe and reliable, easy to install. The grounding lead wire directly passes through the perforation of the detector, which will not affect the lightning protection grounding effect and the normal operation of the facilities.

2. The C-type product is equipped with an LCD display screen that can be installed and used independently, and the grounding resistance value can be observed at any time.

3. It can be equipped with RS485 interface (supporting MODBUS-RTU communication protocol) or GPRS communication, and connected to the user's computer to achieve remote real-time monitoring.
