The Extech 380396 High Voltage Digital Insulation Tester is a professional-grade instrument designed for precision testing of electrical systems. Ideal for maintenance engineers, inspectors, and technicians, this tester supports a broad range of voltage and insulation resistance measurements to ensure equipment safety and performance.
With selectable test voltages of 500V, 1000V, 2500V, and 5000V, it enables accurate diagnostics across a variety of applications. The unit measures insulation resistance up to 60GOhm, giving you detailed insight into system integrity. Equipped with a large 6000-count backlit display and analog bargraph, it ensures readability in any environment.
Advanced features such as Polarization Index (PI) and Dielectric Absorption Ratio (DAR) provide enhanced insulation analysis. Additional voltage measurement capabilities up to 600V AC/DC, along with Min/Max, Peak, and Relative functions, offer flexibility in real-world testing scenarios. A built-in 1 to 15-minute timer helps maintain consistent test intervals, while auto-discharge and safety warning functions ensure user protection.
