Earth Ground Resistance Testers

For safety reason, it is important to check and keep the the earth ground resistance low. This instrument helps you to check the connectivity to the earth and provides you with a reading how well it is connected to the earth.

The resistance can change over time, so it is important to do regular test and check of the earth ground resistance. Keeping the resistance as low as possible. It is here to keep you safe from nasty electrocute shock.
