Split type ground resistance on-line detector
1680 C
Product Description :
On-line monitoring of loop grounding resistance and metal loop
coupling resistance, and grounding condition monitoring.
Product Features :
1. Split Type, no need to disconnect the grounding down conductor, easy
to install, non-contact measurement technology, safe and reliable.
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.
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 & set the alarm value.
5. With RS485 interface, network system can be set up to realize remote real-time monitoring.
