Earth Resistance Online Detector Ground Voltage Tester 0.01-2000Ω Alarm Function

Earth Resistance Online Detector is high-tech
product that our company has devoted to “grounding resistance detection
technology research” for more than ten years, Using precision 3-wire or
simple 2-wire measurement method to test the grounding resistance. Adopt
average value rectification method to test grounding voltage, online detection,
real-time monitoring. User can select RS232 or RS485 communication, according
the protocol MODBUS to secondary development, build network, realize remote
multipoint online monitoring etc.

Earth Resistance Online Detector displayed
by super large LCD, very clear and obvious. The alarm critical value can be set
via the button, and with the sound and light alarm indication. Ensure the high
accuracy, high stability and high reliability of real-time online monitoring of
grounding resistance value in various place.

Earth Resistance Online Detector
Tester suitable for transmission line tower grounding, underground mine
equipment grounding , weather lightning protection grounding, petrochemical
grounding ,communication base station grounding, power substation grounding ,
railway grounding , building warehouse grounding , electrical equipment
grounding, etc.
