About the Hioki 3157
As a ground resistance tester instrument, the Hioki 3157 is designed for demanding applications. Specifically, ground resistance testers measure the resistance of earth grounding systems to verify that ground electrodes meet safety codes and lightning protection requirements. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
