Kyoritsu 3005A Digital Insulation / Continuity Tester

Kyoritsu 3005A Digital Insulation/Continuity Tester

Product Introduction

The Kyoritsu 3005A is a professional-grade digital tester designed for precise insulation resistance and continuity testing in electrical systems. Equipped with selectable test voltages (250V, 500V, 1000V DC), it measures insulation resistance up to 2000MΩ and ensures reliable continuity checks with a 200mA test current. The instrument features an intuitive bargraph display for visual resistance readings, live circuit detection with audible warnings, and an auto-null function to eliminate test lead resistance errors. Compliant with international safety standards (IEC 61010, IEC 61557), it offers robust performance in CAT III 300V environments, making it ideal for electrical maintenance, installation, and troubleshooting.

Product Features
