SEW

The SEW 4310 IN is an advanced digital insulation tester capable of testing at high voltages—1000 V, 2500 V, 5000 V, and up to 10,000 V. It measures insulation resistance up to 2 TΩ and includes features like PI (Polarization Index) and DAR (Dielectric Absorption Ratio) for deeper diagnostic insight. It has a built-in AC/DC voltmeter (30-600 V), adjustable test durations (1-30 minutes), auto ranging, auto data-hold, memory for up to 200 results, and rugged protection (IP65 with lid closed). Designed for safe and accurate use in harsh electrical environments, it’s ideal for testing insulation in cables, motors, transformers, and more.
