Product Description Product Description

Non-contact voltage detector for residential, commercial, and industrial applications. The Milwaukee 2201-20 comes equipped with a work light 3x brighter than the competition. Rated at CAT III 600-Volt, it has a range of 90-to-600-Volt. It is sensitive enough to indicate which side of an outlet is live. Designed for Milwaukee's proprietary accessory mount rail system, it mounts easily onto Milwaukee's DMM (2217) and Laser Temp-Gun (2266) to add voltage detection and a work light to each tool. Nothing but HEAVY DUTY.


Designed to easily mount to select Milwaukee tools, the Milwaukee 2201-20 Voltage Detector with Work Light offers the convenience of two tools in one. Part of Milwaukee's Test & Measure line of professional, cutting-edge tools, the voltage detector quickly and easily identifies the presence of voltage and its work light enhances visibility around the jobsite. The Detector with Work Light comes with a pocket clip for portability, as well as one 'AAA' battery.

Dual-Purpose Voltage Detector/Work Light Provides Safety and Comfort
The 2201-20 is ideal for use by residential, commercial, and industrial electricians, as well as general contractors, plumbers, and service technicians. It quickly determines whether an electrical system or piece of equipment is hot or not, indicates which side (if any) of an outlet is live, and allows you to perform a fast safety check on any electrical device.

The visual voltage indicator--located right on the front of the tool--gives you easy-to-read results, and thanks to its 90-600 VAC voltage range and CAT 600V rating for safety, the 2201-20 delivers consistent, dependable performance.

This compact tool also includes a work light that shines two times brighter than the leading competitor, acting like a mini-flashlight to instantly illuminate dark or enclosed areas.

The 2201-20 comes with a one-year limited manufacturer's warranty.

This is the third voltage detector I've purchased, and the only one that actually works the way I want it to. I need a true non-contact detector, one I can use to test insulated wire, cords, and outlets, without taking anything apart. This one is sensitive enough to get a read on anything I've tried it on, and I don't have to test mutiple points on the line to get it to work. Also, since there's no probe, I have no issues with getting it to slide into an outlet slot; just touch the outlet face, and get your reading. The built-in light could be handy, but I haven't needed it yet, so at this point it seems a little like a pointless add-on, but that's better than NOT having a feature you want. If you're doing renovations, maintenance, or just changing some fixtures, this guy will come in very handy.

The only complaint I would mention is that there's no audible signal, only a warning light. A beep would be nice, but I can live without it.

Expensive Penlight Dec 14 2009

This is my third or forth voltage detector of this form factor, and by far the worst. Yes, it does have a nice LED light that works about as well as all the other LED lights out there, but that's not why I bought it.

It is roughly as sensitive as most other detectors, but not as sensitive as my current Green Lee favorite.

Says Milwaukee on the red and black body.
Has a light.

No audible signal
When it does detect voltage, it is hard to tell because all that happens is a tiny "V" shaped window on one side glows red. This tiny one-sided alert is hard to see in daylight or at any angle other than straight on. Look closely at the pictures in the ad. See the tiny glowing red bolt? Hardly a lifesaver.

Don't get me wrong. I love Milwaukee tools and have plenty of them. But in this case, keep on looking. I know of at least three others that are better, cheaper, and more sensitive.

Update: After writing the above review, I accidently left the device on killing the battery. When I replaced the AAA cell that came with the unit, it was much more sensitive and the glowing "V" was much brighter and blinked. That means the unit is comparable in sensitivity to other units, but you must have line of sight to the "V" rather than the a 360 degree alert like most others. Further, since it did seem battery-sensitive, that could misled users into missing a live wire since the unit's performance can change. The other units I have seem to hold their sensitivity, but the alert sound and light suffers as the battery discharges.

adequate but not impressive July 28 2010
By Nathan M. Schultz - Published on

The button is too easy to press and positioned badly. it is always being turned on which results in a drained battery when I actually need it. The light is nice and volt detector works fine but I would take my Fluke LVD1 Volt Light over this thing any day. The voltage detection in the fluke is pretty worthless but it is the best and most useful clip light I have found so far.

Small and works well Nov. 26 2009

This voltage detector works well and is very small - making it convenient. The light is bright and very useful when crawling around in ceilings or in crawl spaces. All in all, I grab for this about twice as often as my Fluke detector (which is also a great unit).
