The UT273 Clamp Earth Resistance Tester is used for earth resistance test. This meter uses an EBTN screen with a dual display function (the resistance & current displayed). It also has functions such as a real-time clock, data storage, data review, alarm, and automatic shutdown. The tester is characterized by its aesthetic appearance, wide range, high resolution, easy operation, portability, stable performance, and strong ability to resist interference. It is a good tool for electrical engineers.
