Description
Overview
The Hioki 3490 is an analog megohm HiTester (insulation resistance tester) designed for field insulation testing. Using a 250 V DC test voltage, it measures insulation resistance up to 100 megaohm on a clear analog scale, and also measures AC voltage up to 600 V for live-circuit checks. Robust overload protection and battery operation make it a dependable, easy-to-read tool for electricians and maintenance technicians verifying wiring and equipment insulation.
