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

For years now, Ive used some cheaper name brand calipers to do my reloading projects at home and though I get a few years of pretty good use out of them, they always become inaccurate and gritty feeling, so this time, I elected to put in some extra coin and go with quality name brand calipers, and I wish I would have just gone this route before. Ive used Mitutoyo products in my profession for many years and they always hold up for long periods of time. The slide, readout, and accuracy of these are unparalleled when it comes to comparing them with pretty much anyones cheaper calipers. I can always trust Mitutoyo to be what Im looking for. Great price too!

Great caliper.

I was a little leery to buy an expensive caliper with all the other less expensive ones but my neighbor had one and I liked the way it worked. This is easy to use and seems accurate to me. The thumb scroll is easy to use and can do small increments as well as moving faster for larger ones. You can lock it in on a measurement and then compare it to anther item. You can also take measurement, zero it out, take another one that’s thinner or wider and get a difference. I didn’t think that would be useful but I used it the first day. It’s sturdy and well built. Uses a common battery which is easy to change. Overall it’s been a great addition to the measurement line of my tools. I recommend it. Spend the extra money for accuracy and durability.

Unsolicited feedback: With all of the fraudulent copy/knock-offs being sold online these days... I wanted to share with any potential customers that these Mitutoyo calipers are indeed genuine. These were purchased through the Amazon Mitutoyo Store and fulfilled by MSI Viking. Thank you!

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.

Nice build sturdy and very accurate

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.

Between these and Sterrett brand you cant go wrong. These are legit and not clones or copies. I got them for the ease of measuring Imperial and Metric. They are super accurate and work great.

These are nice tight calipers

accurate but battery cap comes off too easy
