Digital earth ground tester
earth resistance tester
earth resistance ground meter

. Description

The meter is applicable to the testing of the earth resistance of the power supply wires, distribution wires inside a room, electrical equipment or appliance, which can done in two measurement modes: Bi-poles or Tri-poles, and it also can be used to measure the earth voltage.

Large digital LCD and backlights applied to the meter facilitate users to read the information on LCD. Besides, the meter is capable of storing up to 100 groups of measurement data, which will not be lost even in case of power cuts so that the user can easily consult the historical data. In addition, the meter can also be used to measure maximum, minimum or average and measure relatively. Auto power-off function has been provided for it.
