Kynup 8 Inch Caliper, Micrometer Digital Caliper Measuring Tool | Dial Vernier Caliper with Stainless Steel, Large LCD Screen, Auto - Off Feature, Inch Metric Fraction Conversion

I was choosing between this and a manual dial caliper, so I ran some bench tests to see how they compared. I used reference blocks from my micrometer set, and interestingly, both the analog and digital units showed zero errors at the 1", 2", 3", and 4" marks. Since battery drain is the main downside of digital tools, I checked the power consumption with a multimeter. This unit draws 17 µA when on and 15 µA when off. With a standard LR44 battery (150 mAh), that translates to about 10,000 hours (or 416 days) of storage life. Even though accuracy was a wash between the two types, I went with this unit because the digital display is easier to read and being able to toggle between inches, millimeters, and fractions is very convenient. It’s been solid so far, but I’ll have to see how the electronics hold up over the long term.

Some things that just cannot do without this. So then we buy one , a good quality product which is a must have. I didn't find anything bad or wrong with it unless you were measuring diamonds ! And if it would do right by you or not I don't know.

Just received. Very good delivery time. Battery was drained when it arrived. On/Off switch sensitive. Suspect caliper turned on during shipping. Replaced battery with one of 2 provided. Seems like a clean, functional design. Easy to use, though a bit heavy. Large display numbers. Easy to read. Easy to change from mm to dec in to fraction in. Very fine readings for accuracy. I have no reliable means of verifying calibration accuracy available. For my wood shop it will be close enough. Quality seems good. Nice plastic case with battery compartment screwdriver and 2 batteries well secured in case. For $20, before tax, well worth the money for my hobby shop.

I got this because I recently got into 3D printing and needed a way to get better measurements. I had originally purchased a different one, but it didn't include the fractions function. Not sure that I'll use it too often, but I'd rather have the option. This kynup caliper was a reasonable price and has, so far, been great. The metal feels durable, and it slides easily for measuring. The plastic storage case is decent quality, and the included extra batteries are appreciated. The tolerances are very good. I know they're not spot on, but that's to be expected at the price. They claim accuracy +/- at no more than .04mm, which seems to be close to what I'm seeing, but it might be slightly more at larger distances. However, the accuracy has been very good for modeling 3D objects for printing. I designed a battery case for my 80V tools, so that I can use it across a couple brands of yards tools. This thing helped me get it almost exact.

Really nice Caliper. Very accurate / precise. Simple to operate and battery lasts a long time. Would certainly buy this product again!

product works as intended, fast shipping,

I got these for home use, not scientific or industrial and they are so much better than I expected for the price. I'm not looking for .001 accuracy although I think it would do that. I wanted it for measuring outside dimensions (like tube, wire, or screw outer diameter) and this thing does it in fractions if you want! I didn't know digital calipers did that. It will go down to 1/128 of an inch, although 1/32 is more than I need. Unless you're looking for scientific accuracy, these are all you need. ....they even come with spare batteries and a tiny Phillips head screwdriver.

I received this tool, yesterday. Under the description, “Details” states that it requires 3 button batteries (type LR-44). It looks like the device requires one battery, and you are provided with two spare batteries. The device feels like it is made out quality, heavy-duty metal. The display is good ! It will take a little bit of use to learn how to hold it correctly. The “resetting to zero” and “switching units” buttons work well. The 2 screws in the top of the device (above the display) require a small (jewelers) flat-head screwdriver. Why are we provided with a Phillips-head screwdriver ? The plastic case is okay, but the right-hand clasp does not lock well. How do customers get a free replacement of a good plastic case, and a correct-sized flat-head screwdriver ? Other customers have pointed these issues out in their reviews. Why are these problems not being corrected during inspection and quality control ? Thank you

Junk.

The product arrived already in heavily used condition with excess oil and many scratches on it. It does work and it does give accurate measurement, but the build quality is not that good. Either go for cheaper one that is as bad as this and does the job just as well or go for a more expensive one that is reliable and good quality.

Ottimo calibro. Funzionale, ben fatto, ben visibile. Il mio compagno negozio è entusiasta soprattutto visto il prezzo

Es muy precioso y funciona perfectamente.

Funciona perfectamente y es preciso (comprobado con un Mitutoyo de +200€). Viene con 3 pilas de botón, tiene autoapagado, estuche...
