Lightning 9V 200VAC Digital Earth Resistance Tester

Digital Earth Resistance Tester GT5105A

This instrument is controlled by intelligent microcontroller chip, with high accuracy and high reliability; it can be used to measure grounding resistance of various power facilities wiring, electrical equipment, lightning protection equipment and other grounding devices, and it can also measure ground voltage. (Note: This instrument is not suitable for harsh outdoor environmental conditions, such as raining, lightning, etc.)

Features of Digital Earth Resistance Tester:

• Digital Earth Resistance Tester possesses the following features:

  1.backlight and battery detection function.
