Overview

The M093 Inductance Tester is a compact, professional-grade diagnostic tool built for technicians who repair smartphones, computers, and other electronic motherboards. Using electromagnetic induction, it lets you quickly verify whether an inductor or coil is still functioning properly — no need to desolder or remove components first.

Whether you run a busy repair shop or fix boards at your own bench, this tester speeds up fault finding and helps you lock onto the problem area in seconds. A simple green LED gives you instant, easy-to-read feedback, so you can diagnose with confidence instead of guesswork.

Choose the power option that suits your workflow: a built-in battery version or a USB-powered version. Both deliver the same reliable detection performance in a pocket-sized, portable design.
