Compact and lightweight, it’s designed for quick, reliable field diagnostics backed by a 2-year warranty.

## Description

The Extech MD10 Non-Contact Magnet Detector is the ultimate troubleshooting companion for electricians, mechanics, and industrial maintenance professionals. Designed to quickly and safely identify the presence of magnetic fields, this pen-sized tool eliminates the guesswork when testing solenoid valves, relays, and coils. Simply bring the tip of the detector close to the equipment; if a magnetic field is active, the device instantly glows with a highly visible blue LED indicator. You can confidently perform diagnostics through plastic enclosures without ever touching bare wires, keeping you safe from potential electrical hazards and equipment damage. Beyond its powerful detection capabilities, the MD10 features a built-in bright white LED flashlight to illuminate dark workspaces, cramped engine bays, and poorly lit electrical cabinets. Its lightweight, ergonomic pen-style design includes a sturdy pocket clip, ensuring it is always within arm's reach when you need it most. Whether you are servicing pneumatic controls, hydraulic systems, or automotive electronics, this magnetic field tester delivers the reliability and convenience required for fast, professional results.

Review: Useful in plant diagnostics - I've just finished testing this. First off, I think it would be much nicer if there was a status LED to say that it's actually powered up, just because the battery could be dead and it would look the same. Others here are bothered by the momentary switch but that doesn't bother me and I like that it can't be left on. The flashlight, which is pretty good, is also a momentary switch. --- Everything I tested was at 24VDC --- Mine picks up MAC valves well, but doesn't see our SMC valves, like the SMC VQ4101 that we have a lot of here. Ice cube relays read well, but the tool has to be near the end with the coil so there's no dragging it across the top of a bank of relays in a panel. Fortunately it has the little flashlight to be able to look the relays over and identify the coil side. Contactors are a little sloppy, they read but trigger the tool from several inches which could lead to false alerts if several contractors are close together. Overall I think this tool is worth the asking price, not perfect, but it's usefulness is greater than the price so I'm doing 5 stars Edit: accidentally discovered the little cap that pulls off the back side and appears to do nothing has a magnet in it to verify the tool with!
Review: Electric tester - Works well

## Questions & Answers

**Q: Will this detect a clippard miniature valve coil?   or just large ones?   i have no idea what magnetic field detection range: 63h, 98h, 401h, 810h is.**
A: It should pick up clippards. However, the light that indicates a field is not very bright. I use it to check on the valves for my irrigation system. They are 24AC and not very powerful.

**Q: Can this tool be used for magnetic field detection on watches?**
A: I'm not exactally sure what you are asking. It will detect a magnetic field that might interfere with some watches. If that is not what you are asking please be more specific.

**Q: Will this detect a neodymium magnetic field?**
A: Of course, this tester will detect. It starts sensing not so strong magnet like neodymium one in the distance of ~15 cm.

**Q: Can it detect GPS cases that use magnets under cars**
A: Thank you so much for your interest in our products. The MD10 will detect magnetic fields if they are located in the available ranges of the unit (63, 98, 401, 810 Henry units). Also, it will have to be found in a short span of the source.

Works well

### ⭐⭐⭐⭐⭐ great for checking electric trailer brakes.
*by J***B on September 19, 2024*

I bought this to check the electric brakes on my camper. It works great. Pull the breakaway switch and look for the magnetic field on the brake drum. I couldn't be more easy.
