KLEIN ET600 Insulation Resistance Tester – Electrical Testing Equipment

The Klein Tools ET600 is a digital insulation resistance tester designed for accurate measurement of insulation resistance up to 4000 MΩ at multiple test voltages (125V, 250V, 500V, and 1000V DC). It also measures AC/DC voltage up to 1000V, resistance, and continuity with True RMS technology for increased accuracy. Suitable for electrical distributors, lighting solutions providers, wire and cable, and switchgear suppliers, this tester supports safe and reliable insulation testing in industrial and commercial electrical applications.
