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

I love these calipers. These are accurate and come in a solid case for storage. Ive made the mistake of buying cheap calipers in the past and finally I did the right thing and bought a pair of these Mitutoyos. Japanese quality!

Leaps and bounds better than the SPI, fowler, husky, cheapies Iv used in the past I have the 12” dial and the 6” digital and they have been awesome.

Every guy wants a caliper but thinks they cant justify a good one, so instead starts with one of the cheap ones. If youre smart, youll only do that once. If youre really smart, just buy the good one in the first place. This is one of those tools you just need to pay up for. That said, this one is very nice but I dont love it. Pros: - Highly accurate - Automatically reads exact position every time! Love it! Never loses zero!! - Doesnt run down battery when not on (like all the cheap ones do) - High build quality Cons: - No detail markings. You have to use the digital display. OK, sure, thats fine 98% of the time. But if its ever out of battery, its useless. - Read that last one again - seriously bad design. This is a really nice caliper, and I love the auto-zero, but Id buy any other model that had detail markings. - Buttons are TINY and still hard to press even when you get a fingernail on it. - Doesnt auto shut off quickly (or possibly at all). Recommended. Its worth the purchase price for sure. I just wish theyd fix the minor annoyances.

Arrived the next day when I ordered it for work. Use it every day at least 8 hours a day and have had no problems and reads extremely accurlitly. 10/10 would recommend if you wanted a nice set of calipers for precision measuring

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.

Constructed to last. Good accuracy

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

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

It’s been over a year since I purchased my calipers and they’ve held up greatly. Within half a thousandth accuracy repeatedly just making sure I’m straight and not canted is the difference and used micrometers to double check and usually within .0001” to .00005” and held up to the coolant droplets and shavings of metal that I constantly wipe off to measure.

Before my review on the operation and accuracy of the Mitutoyo caliper, I wanted to share some key things to look for to verify you have purchased an authentic Mitutoyo Caliper and not a fake one. If youve done some research on the these calipers you probably found some reviews on eBay and Amazon about fake Mitutoyo calipers from China. So first thing, if you find Mitutoyo 500-196-30 calipers listed between $30-$60 they are fake (a good price will usually be between $100-$125). Now that said the one I purchased on Amazon was listed at $95.02 (this was best price I found on the internet, and per the info on the internet and to the best of my knowledge they are legit). So here are the top things I found on the internet to help ensure authenticity: - Mitutoyo is a Japanese company so stay away from sellers from China, and the case should say made in Japan not China - The serial number on the back of the caliper should match the Certificate of Inspection - Mitutoyo calipers are shipped in a sealed plastic packet and are wrapped in an anti-corrosive paper - Mitutoyo calipers include a stainless steel battery (SR44) in a separate package, and it should not be installed - Mitutoyo calipers should include a yellow (3) step set up procedure attached to the lock screw at the top of the caliper - Mitutoyo calipers will always have the same size numerical digits and the inch symbol will be to the right of the digits Now for my review...simply awesome! I recently got into reloading match grade ammo for my precision rifle, and +/- .005 can make a huge difference on your group size and hitting a target at 1000+ yards out. When I first started reloading I was using my old $20 Harbor Freight calipers, which is ok for basic reloading. However I wasnt getting consistent measurements and the Harbor Frieght calipers would always lose the zero position, so Id need to recalibrate after every measurement. In some cases on (3) separate measurements of the same bullet it would vary .005 - .015 and thats not going to cut it for reloading precision ammo, in the pictures below I was able to consistently get the same measurement on all (5) bullets I loaded at (3) different lengths. The Absolute zero function works flawlessly and is a must for me since I use a special adapter to measure the bullet length. So end result very pleased with these calipers and highly recommend.
