Non-Contact Grounding Resistance Online Tester (with Display)
     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.
