Quick Inductance Testing without Removing Board Components
Designed for electronics repair technicians and hardware enthusiasts, this handheld probe-style tester diagnoses inductor conditions directly on the PCB board. Troubleshooting is fast, non-destructive, and highly intuitive.
Fast Diagnostic Response
Perform swift diagnostic checks on circuit board inductors. The double-contact metal probe mechanism allows you to touch and evaluate component pathways instantly, reducing diagnostic timelines on complex mainboards.
Coin Battery Model (Black Edition)
The Black edition is completely self-powered using a rear-mounted button cell battery holder. It features a built-in lanyard hole at the rounded end, providing maximum portability and offline usability on busy workbenches.
Clear LED Visual Indication
Features a dedicated green LED indicator marked "tester" directly on the bare FR-4 fiber board. When the probe makes contact and checks a normal inductor, the green light glows. If the inductor is open or damaged, the light remains dark.

Frequently Asked Questions
💡 How do I interpret the test results?
Place the front metal probe tips directly against both soldering pads of the inductor component. Press and hold the "TEST" button. If the inductor is fully functional, the green LED indicator lights up. If the light stays off, the inductor is faulty or disconnected.
💡 Can I use this on a completely powered-on mainboard?
No, for safety and accurate electromagnetic induction readings, please ensure the circuit board under test is completely powered off and disconnected from external power sources before placing the testing probe on components.
💡 What are the differences between the Black and Blue models?
The Black model is completely wireless and powered by an on-board button cell battery slot. The Blue model lacks a battery holder and lanyard hole, but features a direct Type-C male plug designed to draw operating power from any connected Type-C device.
