Klein Tools ET600 Insulation Resistance Tester is a professional multifunction megohmmeter developed for insulation resistance measurement, troubleshooting, and preventive maintenance on electrical installations, cables, motors, panels, and electrical equipment. Capable of generating 125V, 250V, 500V, and 1000V DC test voltages, the device measures insulation resistance up to 4000MΩ, helping users reliably evaluate insulation quality. With auto-ranging True RMS technology, it can measure AC/DC voltage up to 1000V, while also offering resistance and continuity testing for comprehensive electrical maintenance applications. The backlit dual-function LCD clearly displays test status and measurement results, and the lock function provides hands-free convenience during extended insulation testing. With CAT IV 600V / CAT III 1000V safety ratings, a rugged housing, built-in stand, safety-rated test leads, heavy-duty alligator clips, carrying case, and batteries, the Klein Tools ET600 delivers a reliable, practical, and high-performance testing solution for professional electricians, maintenance technicians, and industrial field teams.
