The Extech 380260 Autoranging Digital Megohmmeter checks insulation resistance up to 2000 MΩ with simple, safe operation. It shows test voltage and resistance on a clear backlit dual display, so results are easy to read in poor light. You can pick 250, 500, or 1000 VDC to match the job, and the range selects itself to save time. It feels solid in hand and suits site work and bench use.
Measurement you can trust
It measures low resistance and continuity for quick checks, and it also reads AC and DC voltage when you need a fast confirmation. The screen stays steady thanks to data hold, so you can log a figure without rushing. Readings remain stable and repeatable, so fault finding becomes straightforward. The simple layout helps new users work with confidence.
Practical design for daily use
An automatic discharge runs at the end of each test and keeps the circuit safe, which reduces risk when moving probes. The power lock feature keeps a test active, so you can focus on the probes rather than the button. A protective holster with a built-in stand supports hands-free viewing and guards the instrument. The case handles knocks and daily travel well.
The meter arrives ready to use with test leads, a carrying case, and six AA batteries, so you can start work at once. It fits well in a bag and sets up fast on site, which helps you keep to schedule. Clear prompts and steady results make it easy to adopt across a team. It is a compact, capable tool for electricians and maintenance teams.
