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

First let me say that like other reviews here I did my homework and checked that my calipers were genuine. The mitutoyo tech support stated that Amazon is an authorized distributor and my calipers were authentic. If you buy from another seller on amazon buyer beware. All the other things checked out, fancy japanese paper, crisp packaging, no battery installed, high quality build. Also, the genuine calipers have a qr code that contains the model and serial numbers. They should match. As for using the calipers themselves. They are great. Checked accuracy vs my micrometer and they were spot on. Display is easy to read. Like most calipers they are easy to use, nothing special. Dont waste your money on junk, buy real calipers and dont regret it.

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.

The only negative about these I am noticing right now is the surface finish and burrs on a few of the non-critical surfaces. They measure fine, but I was slightly disappointed in the fit and finish of those few areas. The other Mitutoyo calipers Ive used havent been like this. Its not a big deal, but it is there.

According to the online counterfeit guides, everything indicates that these are genuine Mitutoyo Calipers. The quality is superb. I am happy with the peace of mind of having a reputable name-brand product so that I dont have to wonder if they are accurate. I have had them every day for weeks now, and I have not had to recalibrate them once. If they dont indicate 0 when I close them I can be sure wiping the tips is the solution. They continue to reflect proper dimensions even with the display off, so if I turn them on while they are open I still get an accurate reading. According to the enclosed certificate, the accuracy is +/- 0.02mm or less for the entire length of travel. Movement is smooth and controlled. For over $100 they werent cheap, but I feel like they are a great value. If there are better ones out there, I dont want to know what they cost.

I bought this for my silver jewelry making. This one is so much nicer than my old one the only thing missing from this one is the fraction function that I have on my old one has but that’s minor in comparison. I will never use any other caliper, I also payed the extra money for the piece of mind and got the calipers with the certificate of calibration.

I think from everything Ive researched that l may have got lucky with this pair being originals. Mine passed all the fake tests but Im not a machinist and of course maybe the forgers have improved their game but just Incase l feel like these are exceptionally good in fit n finish and accuracy as far as l can tell. All the best out there everyone.

I have been using a dial caliper for hand loading for years. I recently decided get a digital caliper to make it easier to read measurements directly when using attachments on the jaws of the caliper. The first digital caliper I got was an inexpensive (~$25) instrument from a different manufacturer. That was a mistake. The inexpensive caliper was essentially useless for my purposes. Its consistency in reading was terrible. Frustrated, I decided to just spend the $ and get a good instrument (buy once cry once). I decided on a Mitutoyo 500-196-30 - I was not disappointed. What a caliper! Very accurate. Very consistent. Very easy to use. Very easy to read. Very good battery life AND uses a commonly available inexpensive battery. I cant find anything that I dont like about this caliper! I dont usually write reviews unless the product or customer service is extraordinarily good or extraordinarily bad... This caliper is that good - worth my time and my $ (and yours too!) Buy with confidence!

As of this writing, Im eight months in and I grow increasingly happy with this investment. Im far from a heavy user of precision measuring devices. Because of that, the extent of my caliper investment was a couple twenty dollar wannbes. Their dependability was such that I avoided using them, except when there was no other option. Each time I wanted to use the cheap ones, I had to replace or install the battery. Now, with the Mitutoyo, I have no qualms about reaching for them to, for example, determine the inner and outer diameter of bearings for my pieces of equipment. Unlike the cheap versions I had in the past, these are ready to go with just a touch of a button. Regarding accuracy, these go well beyond anything I need, for what Im dealing with (bearing sizes, bolt sizes, etc.). SIDE NOTE: Going by information others posted, mine is the genuine article. P.S. I gave the other two, battery eating toys away.

I have this one for the workshop. https://www.amazon.com/gp/product/B01LPIWAYO/ I wanted a second one for inside the house. So I bought this caliper. Knowing what I know now, Id have spend the extra money to get the one I bought before for 2 main reasons. 1 - This one doesnt auto-power off. 2 - The buttons are small and practically flush with the plastic face. Neither of which was an issue with the other one. The other doesnt even have a power button it powers up and down automatically. Functionally it works fine and seems well made. Id just rather not be annoying by trying to press buttons it should be easy to press. Or opening the carrying case and noticing it was still turned on.

Works well.
