Description
Overview
GAOTek the high-quality soil tester is designed to measure earth electrode resistance and soil resistivity. For use on large or more complex earth systems, which include communications earth systems and difficult test environments With the latest technology in a small-sized, robust, and easy-to-use instrument, this series of earthing resistance testers are mainly used to test the earthing resistance of transformer, lightning-proof system, high-voltage power tower telecommunication equipment, etc, providing a perfect solution for the earthing-resistance test There are three models of this series, including Meter A, Meter B, and Meter C, which can meet various requirements of different customers.
