Earth Testing

Group Overview

Digital Earth Testers

 

The installation of satisfactory earthing systems is an essential part of electricity supply and wiring safety. It is also very important in many communication systems. All earthing arrangements should be tested immediately after installation and periodically thereafter. Earth testers enable both earth resistivity and earth electrode testing to be carried out.
