Mitutoyo 500-196-30 Advanced Onsite Sensor (AOS) Absolute Scale Digital Caliper, 0 to 6/0 to 150mm Measuring Range, 0.0005/0.01mm Resolution, LCD

Was very skeptical especially with all the fakes. I bought through LLC Amazon, and after doing quite a bit of research I believe these to be real. There are 4 zeros before the decimal point when in inches, and 2 zeros before the decimal in mm, the finish is very nice, even the box is very sturdy. The battery is the correct SR-44 and comes in its own plastic packaging (in the caliper box), the zero button has to be held when you fit the battery, when doing this make sure you put squeeze them closed to ensure correct readings. I contacted Mitutoyo to ensure the certificate of inspection of genuine as the signature and stamps look to be printed on. They viewed photos of the documents and believed them to be authentic, I think Mutitoyo must be printing signatures now... I also saw a review of someone else which posted the photo of this card, and it had a different serial number to mine which is another indication the item is authentic. For the record my serial ends in 554 so chances are if we all have different serial numbers the item is authentic as they match the item and certificate. I hope this helps someone. Thanks.

This device is easy to use and understand which is just what I needed as I am learning the machining trade.

These are nice tight calipers

I read a number of reviews that said other cheaper brands were just as good and there was no reason to pay more for a Mitutoyo. Bought the Mitutoyo and an iGuaging to compare. While they both may be accurate, the Mitutoyo has significantly better fit and finish, sturdiness, etc. Everything about it feels quality. Kept the Mitutoyo and the iGuaging went back.

I am a hobby machinist constantly overhauling flat head engines. Having a repeatable accurate vernier caliper is a must. This is a quality tool at a reasonable price.

Purchased this to replace a Mitutoyo caliper that Ive been using for over 15 years. This set works great.

I have never used one of these tools before, but I was able to figure it out pretty quickly and easily. It helped that I watched some videos while I was waiting for it to arrive of course. It also comes with directions in a whole bunch of different languages Japanese being the first and English being the second and so on, and I am lucky enough to have my husband give me a few pointers as he is more familiar with these tools. The tool seems to read accurately and Ive had fun playing with it by measuring random things around the house. Oh and one important thing to note, if you are a newbie like me, be careful how much you push on the wheel when measuring as this can cause a lot of fluctuation and false numbers in your readings. Dont forget to shut if off when not in use as I guess it does not turn off automatically (forgot to get one with that feature as Im forgetful, oops). The battery comes with it, but you have to install it yourself, which is easy to do. I did not see or read the caution on one of the smaller white papers (they are all white papers) before I opened the tool, maybe they should make that page a caution yellow or red color to grab your attention better, anyways it said to be careful handling the brown paper that is in the bag with the tool as it is a special paper called Ferobrite used to protect the tool from corrosion. I didnt realize that and touched it anyways, nothing bad happened but I did go wash my hands after I finally saw the warning paper. I got this tool to use with 3D printing primarily and I cant wait to start crafting my own versions of stuff. My husband will also be using it for his own various projects. He is the one who recommended this brand stating that it is a great brand for some really accurate measurements at a fair price (he does mechanic work as a hobby and as we need for our vehicles along with other technical stuff that these tools are generally used for, he has a lot of neat hobbies) Overall it seems like a good purchase and Ill update if that changes.

This a very accurate, easy to read caliper. Im not a digital caliper kind of guy but this is one I dont mind using. I have a few Mitutoyo calipers and gauge blocks and they just make affordable, quality tools. I would definitely recommend spending a few extra bucks and buy these instead of the cheaper made in China crap. Youll be happier in the long run. The only con is the onsite memory is glitchy, doesnt keep the reading. Im not going to use that feature anyway so...I dont care. Hope this helps.

I’ve used these calipers and many other mics and tools offered by Mitutoyo in my career. They never failed me. Tough. They take the oily, dirty jobs you are work on.

I ordered this to measure shims while doing a valve adjustment. The first order got lost but I had to wait another week for Amazon to make sure it really was lost before I could reorder and then another week plus for it to arrive. Did the job with my brothers digital caliper that cost a third what this one does and it did work fine once I figured out it was always .02mm over. Is this one worth three times the cost? I appreciate the craftsmanship, precision, fit and finish of the Mitutoyo and the pleasure using of a premium tool so for me it is worth it.
