Split type ground resistance on-line detector

Special Features:
<br>
1. Split Type, no need to disconnect the grounding down conductor, easy
to install, non-contact measurement technology, safe and reliable. <br>
2. The grounding down conductor directly passes through the detector
perforation, which does not affect the lighting protection grounding effect and the normal operation of the facility. <br>
3. The detector with an audible and visual alarm. KM 1680C with LCD that can be installed and used independently.You can observe the grounding resistance value at any time &amp; set the alarm value. <br> <br>
5. With RS485 interface, network system can be set up to realize remote real-time monitoring.
