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

These seem like genuine Mitutoyo calipers. Functional, everything seems fine/new. Only 3 stars, because it was shipped in an envelope with no padding. It has a hard case, but it was probably banged around a lot during a shipping. Not adequate for a precision instrument.

Incredible, accurate, bought in 2019 and battery still going strong in 2023. Probably been dropped about 50 times and still work just fine.

This caliber is accurate and perfect, the best thing is that it is made in JAPAN, quality product, it joins my other mitutoyo 8 inch caliber.

For what I received, this was the Real Mitutoyo 500-196-30 and not a Chinese knock-off. For the battery, I used a 357 but not the SR44 which came with the caliper. The trick was removing the battery from the compartment since the 357 is a touch larger than the SR44. For this, I used a small piece of duck tape to pull the battery out of the compartment. For the caliper, I only use this when needed. Most of the time, it remains in storage. As such, I do not want to leave the battery inside when not being used for a while.

does what it is designed for with absolute precision...

Great craftsmanship, feels sturdy and doesn’t loose zero like cheaper calipers

I work at a machining shop where I have to get thousandths quite often-while its obvious that its accuracy is at its highest by being unworn, every time I zeroed with the jaws shut, it held a perfect zero no matter how hard I tried to press it together. Likewise, if performing the same measurement and done the same way, the results matched to the 5 tenths with no hesitation. Came with quite the little calibration test sheet, which was nice for the guys who calibrate the tools at the shop. Also, while its just a feel thing, it glides when measuring. Its the smoothest set of digital calipers Ive handled. While the jaws arent the fancy super-hardened steel some other options have, they do very well and show no sign of problems. Very happy with them, especially knowing I dont have to try to find one of the regular shop calipers for ten minutes.

This is not a cheap Chinese nock off. Smooth action and holds it calibration well. The only reason I rated “easy to use” as a 4 was because it doesn’t have an auto on feature like my 12” Mitutoyo. Mitutoyo evidently did this to help save the battery, but this isn’t the fault of the seller.

Great craftsmanship, solid in the hands and when you need to be exact this is exactly what you need.

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.
