Description: This smart SMD tester is essentially a pair of multimeter tweezers. This allows you to troubleshoot circuits with small SMD parts without having to fumble with large probes or long wires. Test resistors, capacitors and diodes one-handed!

Customer Comments

  • Wow, fairly cheap too!

  • These work quite well, except for two issues: - the probes are about 1.2mm thick at the tip, which makes testing 0603 parts a bit clumsy. They can be easily unscrewed if you want to file them down, but this may affect the accuracy (there doesn’t appear to be a way to calibrate it) - the lower bounds on the ranges (300Ω, 3 nF) are somewhat limiting. Caps in the pF range are often used with crystals, and having them measure in the nFs is quite confusing. This is definitely a case of PEBKAC, but having the minimum ranges printed on the case would make things a bit easier.

    Conclusion: they do exactly what the spec says, but you’re probably better off just getting some tweezer probes for a good multimeter.

  • 30000µF? Is it right? I guess it’s too much for such a cheap device…most multimeters, that are more expensive than this little tweezers, are able to measure just within 200µF. = ]

  • Some of you guys are looking for inductance meters.

    Here is one trusted in the ham radio community. $100 kit or $130 assembled. But not smd specific.

  • Been using these and love them. The Auto mode is very handy when measuring resistors and capacitors because it with toggle between them automatically (as well as diode testing but I hardly use that portion.) The documentation is a little fuzzy, but these power off automatically after 10-15 minutes of use, unsure if that resets from taking a measurement. Hold FUNC while they’re on to turn them off manually. A sliding switch would have been useful here!

    They don’t have amazing resolution or range for tiny cap values, but if it can grab a rough/close value I prefer these to a +$100 LCR meter I use at work, think DMM with annoying tweezer wires. If only they could read inductance also!

  • (Clap clap clap) now one that will not break the bank.

  • with large probes are long wires.?

    • Also, they are missing a comma at “Test resistors, capacitors and diodes one-handed!” between ‘capacitors’ and ‘and’.

      • That’s sometimes called the “Oxford Comma”. It’s not required. Personally, I think it looks better aesthetically to include one but maybe Sparkfun doesn’t.

        • It reads more smoothly without the comma, in my opinion. And, of course, MY opinion is BEST. (I’m being sarcastic)

  • Hello 10x cheaper!

  • How about a set of meter cables that has tweezers for probes, so we can use them with our normal meter?

    • make ‘em yourself for about $0

    • Check eBay for that until Sparkfun start carrying it. You can get one for less than $10 dollars.

  • Too bad it doesn’t measure inductance. I guess if it did, it would not cost $28.

  • The naming sounds like a rip off of Advanced Device’s ‘smart tweezers’.

    • I’m sure they’re not the first company to call their product ‘smart’.

      • True, but this product is very similar in function and design to the more popular (and overly priced) smart tweezers.

        • Companies will do that so you’ll make that distinction without any legal implications.

          Arduino: Seeeduino, Freeduino. Pretty sure Seeeduino didn’t invent the Arduino template, but now I can remember Seeeduino makes Arduino-like stuff!

          These probably are a “Smart Tweezers” knockoff. :)

It is handy, light and quite accurate. I keep it with me all the time. I simply fell in love with it.
