Featuring an extra-large 4,000 count display and built-in non-contact AC voltage detector, the Extech EX330 combines an autoranging multimeter with a built-in non-contact AC voltage detector.

5.0 out of 5 stars Very good multimeter, great feature set for the price April 24, 2010

By Norm Ally Wright

I've had this meter for a bit over a year now and am very happy with it. It has a good number of features along with the temperature probe which is a nice bonus. Have used on quite a bit of items. House, Auto, Computers, even some standard batteries that got mixed up. Only reason I didn't give this meter 5-stars is because it didn't come with any alligator clips. As a couple others commented, the meter does fluctuate and skip around a bit using the normal straight contact tipped wires until you get your hand steady and have it on good contact sites. However this is due from just getting a good connection not really the meter itself. I highly suggest buying a set of alligator clips if you have this or plan to buy this multimeter. It totally solved / stopped the contact issues and I get a fast solid reading every time I use it using the alligator clips. Yes Fluke brand multimeter's are considered the best ones out there. Also the most expensive, so save 2-3x your money and be more then satisfied with this unit.

edit: I just wanted to add in, I should of gave it 5-stars originally. Was 4 stars, added a proper 5th star. Alligator clips would of been nice, but lack of didn't deserve a star reduced. Alligator clips are not always included. If your using the standard probe tips just make sure your contact spot(s) are cleaned well and maintain a steady hand. Or again use some kind of clamps or clips, you can buy them for a few dollars here. Once the probe has made good contact for second or 2 with no movement it has never failed me and given a good read out. I didn't re-edit my original post just added this as I felt it was needed.

4.0 out of 5 stars Decent meter, but temp probe was NOT included as described December 27, 2010

By James Paul

I ordered this meter to replace a 20 year old meter I keep in my mobile kit. The product description and title make it very clear that the remote temperature probe is included with this meter, but it was not. I don't have immediate use for the temp probe, but I do need to start using the meter right away and it would be inconvenient to return it just so Amazon can replace it with the same item to see if the replacement comes with the probe. Sadly, it's simpler to just tack on a type K probe to a future parts order for a few bucks than deal with the hassle of getting Amazon to ship me the probe I paid for.

In general this seems like a decent low cost meter, built fairly well and to safety standards. It's not a high-end device, but I consider it to be in the top 2 or so in this price range for features and accuracy. It also did pretty well in the EEVblog shootout, which is one reason I selected it. I look forward to seeing how well it holds up to my abuse. So far I have no complaints about the meter itself, only that the temperature probe was not included as clearly stated by Amazon. This was not a third-party order or fulfillment order, it was sold to me by Amazon.

4.0 out of 5 stars good for hobby jobs December 11, 2010

By Felix E. Rusu

I know I couldn't expect too much out of a $60 multimeter but as an engineer I thought I could expect more. It had the best rating on the eevblog $50 multimeter review and also highly rated by adafruit so that's why I chose this one. It works OK but the thermometer is next to useless, the capacitance is not accurate and very slow. There are a few other annoying things about it, but when you look at other multimeters, you'll probably want the one that sux less in the $50 range. I like the no-touch current sensor, a nice add-on. If you want a thorough review of it go to eevblog.com and look for the $50 multimeter video blog. If you're not crazy about accuracy and only need it for hobby work, it's quite good. If you want real reliability and accuracy get a fluke, you won't be sorry.
