Digital calipers are an absolute essential. Here at SparkFun we use them all the time. These premium calipers come with an extra battery and auto shut-off. Measurements can be taken in either metric or standard. The calipers are 6" in length and make a great addition to any tool set.
These come with two 1.5V LR44 button cell batteries.
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

For the money it’s pretty good and repeatability was better than I expected. But that’s about the only good thing I can say about them. The slide action is incredibly rough and makes a horrible grinding noise that makes you wish you feel like you’re getting a root canal.
At first I thought maybe I was just unlucky but then I came across this: https://www.youtube.com/watch?v=WvszAb0Y0Ec
If you really need calipers, get these, they’re more accurate than using a potato, but if you just want a pair, save up for a better set.
Sorry to hear that your unit was so rough. I keep a pair on my desk that I have used for many years. Contact us if you would like to try to swap them out. https://www.sparkfun.com/returns
I just got a 3d printer and got these to measure parts. They work as expected. No problems using them.
Out of the box, it didn’t work. The reading was jumping all over the place, and eventually, I couldn’t turn it off anymore (pressing the ON/OFF button didn’t turn the calipers off).
But you can’t really complain for $10. Sparkfun made it right though, so A+ to them.
I’m sorry for the troubles. I’m glad we could help get you taken care of. Cheers
These are not good, spend more.
I bought this a while back. From the very beginning, it was pretty much worthless. You zero it out, and then as soon as you move the sliding bar, the zero point begins to fluctuate wildly. I’ve never been able to get the same measurement twice for any target.
Had it put away in a cabinet; but, ever the optimist, I pulled it out again today and found that, yes, it’s still all over the place.
I really don’t think you should be selling this product at all. It’s really a shoddy piece of engineering; not worthy of the SparkFun line of products. At this price, I suspect that most buyers, like myself, are inclined to write the purchase off rather than taking the time to request a refund or replacement.
Sorry that 1 star is the lowest rating I can give it.
After seeing the response to my post from SparkFun’s Single T, I do regret that I did not take the time to pursue the matter through Customer Support. After several frustrating attempts to make the device work correctly, I, like many others, simply reasoned “what should one expect for 15 bucks?”.
I will await reception of the replacement before making any further judgments on the usability of the device.
But I should not have forgotten that SparkFun is one of the most reliable and supportive sources of products, ideas, and support that I’ve ever experienced in years of building embedded devices. And your offer to supply a replacement, even long after my purchase, speaks volumes about the level of attention that SparkFun gives to its product line and its customers.
Thanks again to SparkFun for the critical support you’ve provided to my efforts.
Hi, I have hand tested a replacement and will be sending that off to you. I’m sorry that your device didn’t work as it should. We’re a simple email away from assisting you. I wish you contacted us sooner. Thanks.
It’s a very good calliper, it seems robust and frendly. It would be better if the battery’s cover comes with an screw or security system for prevent open battery’s tape unintentionally , but it’s a great Calliper, Really Really Great Calliper..
Pretty accurate for $15! The metalwork is a little rough, but I expected that. One thing to watch out for is the auto-off feature and the on/off button don’t actually turn it “off”.
The display turns off, but there’s still a charge going to the LCD which you can see in the silhouette of the number segments.
The battery on mine lasted for a little under a year, but I’d recommend removing the battery if you aren’t using it for a while. I have a feeling the manufacturer knew about that when they put the little cut-outs for a couple LR44 cells in the provided case. ;)
This set of calipers does indeed have some accuracy issues. Mind you, sometimes it works alright, but more times than you might expect the reading doesn’t seem right and if you close them back to what should be zero you find that the reading is a bit off. These are alright though. As some others noted they’re okay for the price and all in all I do find them useful.
Unfortunately this product does not work. You cannot turn it off, so the off/on button is basically useless! The measurements are not accurate and fluctuates wildly, even when not using and after zeroing it. To put it simply, this thing doesn’t work.
Sorry to hear about the issues with the calipers. Have you contacted email@example.com about this issue? Based off what you describe, it sounds like you may have received a defective unit, and could be eligible for an exchange - firstname.lastname@example.org would be able to help determine.
I suppose there’s lemons in any cheapish product, but the one I got has been working great for several years now. I think I’ve changed the batteries twice. I’m not a machinist (and don’t need those kind of tolerances). This has been perfect for creating 3d models of parts and for the most part replaces the ruler on my desk : )
As a little background I’m used to measuring things with Mitutoyo Calipers at work ($200+). The first thing I noticed is that this Calipers don’t run as smoothly. I fixed that by adding some oil to the back rail and they still don’t run as smooth but way better than before. Accuracy is pretty good, I actually expected less. The only defect I’ve found so far is that there is some kind of problem with the auto-shut down feature so I have already replaced the first battery with no more than 50 uses. I found a post somewhere on the web where they suggested to add an external switch, maybe I’ll try it in the near future. Anyways, for the price this Calipers run they are a great deal if you are not looking for ±0.01mm accuracy or more!
I got these a little over 2 years ago, and they recently stopped working, the reading will sometimes skip to a much larger value, or show exactly one-half the actual value (I suspect one or more of the greycode pickups are broken). Without any way to repair them I’ll probably spend a bit more on a Neiko set
