This product is designed forGrounding resistance test, invulnerable to high or low temperature,corrosion,fire. Non-contact measurement, safe and reliable, Easy of installation

Grounding down lead goes directly through the detector perforation, not affecting lightning protection grounding effect and the normal operation of the facilities

With display and Alarm, it is enable to observe the resistance  and  preset Max value

Application:

Electric transmission line pole grounding

Underground mine device grounding

Petrochemical engineering ground

 

Provides power supply and RS485 signal interface, and standard MODBUS-RTU communication protocol，which user can do secondary development to realize remote monitoring.
