ALLOSUN Digital Multimeter/DMM/Multi Tester Amp/Ohm/Volt Meter/Diode and Continuity Test Pocket Size (EM3081)

First up, the claim in the product description that this is the size of a business card is exaggerated. All-Sun should drop that claim, it's doing them no favors.However, that said, this digital multimeter *is* tiny. It's most likely smaller than your phone — but if so, it's probably thicker too, so that balances out. The important thing is, it's small enough, and *rugged* enough, and *inexpensive* enough, that you can buy one for every vehicle you own, and just tuck it in the glove box (or, on your motorcycle, in the tank bag or under the seat) and forget about it until you need it, and the day you need it, it'll be there. Test leads are tucked away inside the clamshell case, which also serves as a stand.The EM3081 has ACV, DCV, current and resistance modes, plus a diode continuity test mode, and ranges up to 600V AC/DC and 2 megaohms. Current measuring mode is fused at 200mA. The rotary mode switch is easy to use (make sure you remember to turn it off after use so you don't drain the two silver-oxide cells it runs on), and the LCD display is large, sharp and easy to read. (It's not backlit, though. If you're troubleshooting at the side of the road at night, you'll need a flashlight. But then, you won't be doing much troubleshooting at night without a good flashlight anyway.)Long and short: If you know what to do with a digital multimeter, you could do a lot worse than just keep one of these in every vehicle you own. Sixteen bucks could save you from being stranded or having to call for a tow.Two Technical Thug thumbs up for the EM3081. It's no Fluke, but it's all the multimeter you need for roadside troubleshooting.

Nice Product. Very compact yet provides all the functionality you generally need. Includes a continuity feature that others do not. I find I use this in troubleshooting more than the other functions. The clip and probe mounting system is better than other models of this type. This is the perfect meter to throw into your travel tool box: compact yet very functional.

Works great easy to store, only complaint is that the wires are to stiff

Just the right size. I keep it in my backpack because you never know when you will need to measure an electric potential...For the price it is of the expected quality, but I do not see any issues in the construction. It is very helpful for checking Lipo battery voltages when you don't have or want to carry around a full size multimeter. The test leads and screen are protected in the integrated case. You have to squeeze in the leads and wires, but it is not too hard. You also have to select the type of measurement (current, voltage, continuity, resistance) in addition to the range. I guess this keeps the number of positions on the selection wheel low.You could fit this in your pocket, but it would not be comfortable with keys, a wallet, or phone. I would recommend for anyone who needs a portable, no worries multimeter.

This small multi meter is a bit larger than expected and some of the base features could be refined... but it's a budget meter. It takes/comes with 44 button batteries (better batteries may work) and has no clip battery cover, so when the cheap batteries go you have to break out a screw driver. The leads are hard wired and don't fit that well in the lid, so are regular use the leads will likely be damaged. There is no auto off so I'll likely forget to turn it off. The pluses are once (off) and closed (once you get the leads tucked back in) it a fairy compact unit, it's easy to read and operate and it is fairy accurate for its cost. It you plan to keep it around to keep batteries, check simple connections, ect it may be fine (maybe). I wouldn't use it for much more. But it's a compact budget meter and I've seen mildly better for the same price. I bought it to check various rechargeable batteries without having to run around getting a better/bigger VOM... and it'll be fine for that.

I've used several of these from Radio Shack -- it is small enough to use a velcro "around the wrist" band and I fix the unit to the velcro -- which means when I'm up in the grid I can do one handed "reads." (I velcro the probes to my index and ring fingers and can poke them into sockets to determine if they are live.THIS one came dead. Batteries were working (I checked with my Fluke) but the probe leads were poorly soldered (cold solder) and it looks like someone tried to repair it and dripped solder into the circuit board. I strongly suspect I got a "fast recycle" unit -- returned "repaired by hand" then sent out in the field again. Fry's used to do this and it cost them their business.Do not trust these guys.

Contrary to some reviewers complaints, this meter does come with batteries, but one must put forth the effort to remove the 2 bottom screws and pull out the clear plastic tab that prevents one of the LR-44 cells from making electrical contact with it's battery contacts.Once that is done, don't forget to use the 4 position slide switch to place the meter in the desired voltage/resistance/current position, remember the max current is only 200mA on DC only, so it's best to use a higher current meter if you want to read transient inline current readings.Another thing to consider, 200mA may not seem like a lot of current, but it only takes 30mA of current at pretty much low voltage levels to interrupt the heart's rhythm and potential kill a person, so be safe.I really like the meter test probe cord securing set-up, it prevents too many kinks and if one is careful to remember some of the earliest lessons about test probes in electronics class, avoid changing the natural bend of test probes because over time if you insist on changing the bend points, the wires inside will bend and kink until they're no longer capable of accurately measuring the designed meter's under test electrical levels.
