Smallest multimeter

[KenD]

What is the smallest multimeter you've seen? I'm looking for something that I could carry on me all the time (I have a regular dmm and an ohm checker at home) so I'd want it to be as tiny as possible. As it will be for on the go quick checks it doesn't need to be terribly precise. I live in Europe so I won't be ordering from the US, but feel free to provide links to over there as well. That way I'll be able to check what's out there and be better able to compare to what's available over here.

Thanks in advance!

Let me google that for you

the smallest Ive seen is about the same size of a pack of 120mm length cigarettes...

I found some that are about 10 x5 or 6 cm. Curious if there would be anything even smaller

I was given 4 Uni-T 10A mini "shirt pocket" multi-meters a year or so ago, at an electronics trade show. They're about the size of a old style Motorola Razr flip phone, but thinner. Weigh maybe 6-7 ounces. Real cheap at around $10... perhaps the reason they were giving them away. ;-)

My favorite however is the Amprobe PM51A. It's smaller, lighter (than the Uni-T)... not inexpensive for it's size, but of much better quality than the Uni-T. The only down side (at least for me) is it doesn't have standardized test lead ports, so I can't use my Tech Thing milli-ohm adapter with it.

Couldn't find the exact size of that one but it certainly looks tiny

The Amprobe PM51A is 113 mm (4.45") x 53 mm (2.09") x 10.2 mm (0.40"). A bit tall... but nice and thin.

Just do not try to use smallish multimeter for coil resistance measurements.

That is very cool.

Uni-t has meters with various feature sets in that small form factor, found a reveiw on one of them

I looked at all those small meters, but I didn't like the hard-wired leads, so I went with a Uni-T UT-33A. It's smallish, but not as small as you're looking for.

Will something like this work:

At the risk of speaking for the OP, I'm guessing he's looking for something to accurately measure resistance below 1ohm. It is definitely small though!

Yeah, with a 4A Max it isn't good much below an ohm. Also you can't use it for short-testing since it is powered by the PV...
It is kind of a neat toy though, and for what it does it works pretty well. Hard to read the numbers while you're vaping, though!

The meter measures 5.1 x 3.1 x 0.6 inches...

That's an awfully big credit card.

Yes, and I'm also (and possibly more importantly) looking for something that'll let me check my battery voltage when I'm travelling. I did find a smallish dmm on fasttech (10 x5 or 6 - too drunk at the moment to find the link, the record release of Crucified Barbara, check out the band), but it would be great with something the size of a match box (a box of lucifers in Dutch, I kid you not) - not counting the probes of course. I'll not find anything that small I'm sure, but one can hope...

Another place to look for meters is Deal Extreme. DealeXtreme - Cool Gadgets at the Right Price - DX Free Shipping Worldwide They have several small ones - the type that come with a "fold over" cover with leads permanently attached. And others with detachable leads. For the sake of testing battery voltage and checking for shorts any of them would work fine, but as with any of the low end meters they don't do well for accurate resistance readings.
