Product Description
Digital Earth Ground Testers UNI-T UT521 Electrical Earth Voltage Device
Introduction
Grounding Resistance Tester UT520 is designed with intelligent micro-controller chip
to maintain high accuracy and reliability.
It can measure earth resistance of earth
ground devices for electric power installations, electrical appliances,
lightening protection systems, etc, and also measure earth voltage(It is highly
recommended not to use the Tester under severe outdoor environments such as raining or thunder).
