Digital Caliper, Caliper Measuring Tool with Stainless Steel, Electronic Micrometer Caliper with Large LCD Screen, Auto-Off Feature, Inch and Millimeter Conversion (6 Inch/150 mm)

I have used this item for close to a year now. Still Zeros out every time. With repeatable results. This comes.with 2 extra battery and a hard case to place and store it safely away. Reads in mm. And half of a tenth of a thousands of a inch. This is my 6th pair of calipers and so far it's looking like the last pair I need.

I'm a journeyman machinist, so maybe more picky than I should be. I can tell you this is a very accurate instrument, if used correctly, that is, don't expect to have an accurate measurement if you push too hard on the caliper when doing OD measurements, or have it at at even a slight angle when measuring a shoulder, or depth. I ran tests on my precision blocks, and 1, 1.5, 2.0 cylinders. It was within .0005-.001 accuracy. I didn't deduct a star but what I didn't like about this caliper is it only went up to 5.940", not 6+ inch range. I had to carefully mark the holding screw at the back, then grind a flat, then reinstall it to allow the caliper body to go back far enough to measure 6+ inches. I can do that but other users may have trouble if they're not machinists used to handling 2mm diameter threaded screws. This caliper doesn't display fractions, like others such as the Qfun seller. Not an issue for me but some may want this capability. But overall it is a nice caliper with all the numbers being large, not just the first couple numbers, then the rest of the reading has small numbers, like some calipers display. Also, the battery is easy to install, when needing replacement (they supply two, one in it, and another when needing replacing). Some calipers require a screwdriver to remove a cover.....deal breaker for me. I like the individual buttons on the front, not under the display face bezel. The dual/trio function calipers that have the on/off/zero are OK but you have to toggle through the button presses to get to what you want to do. So I give this a high mark, almost equal to my Qfun, and Acemeters, and slightly better than my $100+ Mitutoyos. Wait a second....Mitutoyos score lower? Yes. The display on mitutoyos are smaller than these or my other favorites. In odd measurement conditions, you need the largest display possible. Second, mitutoyos never turn off, unless you shut them off. If you forget and leave them on, then you need a new battery. This and my other calipers auto-turn off BUT, they keep the last setting, so you don't lose a reading or if you locked the caliper in place at a certain reading. If it shuts off, you just hit the on button and it'll display the exact reading last entered. Overall a nice unit, well worth the money.

Great for the price. Very good quality

Purchased and received this IP54 digital caliper. Upon opening I did a quick check to make sure everything was working and if I had any questions. So far so good. I checked the accuracy and found it to be quite accurate ... as accurate as I will need. This is very good construction and easy to keep clean, which is very important. Periodically it would be a good idea to wipe it down with a soft, clean rag especially prior to making your measurements. I found the battery location very easy to open/close and to change the battery. Make sure the + is against the holder and the - is facing up. Two extra batteries come with the caliper in addition to the one that is already installed. If you want more spare batteries my unit uses Lithium Battery 3v CR1632. I highly recommend this caliper.

These are decent for the price. They work, come with extra batteries, nice weight to them and slide easily.

Not bad, good price. Pretty sturdy.

Seems well made and accurate and easy to operate

Yes! Works like you would expect.
