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

This tool is ALL THAT U COULD EVER WANT IN A CALIBER..... However buy the right lenth dont make my mistake. When the 6 one is extended over 3/4 the HEAL of you hand go over the end and puts pressure on the depth tool/gaudge and could be EASILY be BENT, No Fault Of The Tool. So may I suggest buy the 8 one if youre going to mesure items longer than 2 to3 , save the stress of bending your depth gaudge As in the boating industry, buy your second boat the first time, just saying

Ive used these for 20 years at work so Im very used to them. Now I have a set of my own! Smooth action, big readout, bigger than the older style, that resolves 0.0005 inch in five full-sized digits. Simple to flip to mm. Does not turn itself off (a good thing!). Super stable---maybe due to the submicron internal resolution? Great finish and fit. Thumbwheel feels good. Batteries, per catalog, state 3 to 5 years but I suspect longer based on past experience---and I have left them on over many a weekend! This is not not a review of a counterfeit. This purchase was fulfilled by Amazon and their inventory control is impeccable. These calipers came in a sealed bag with a piece of Ferobrite VCI paper. That was placed in the one-piece molded case. On top of that, stapled all together, was the Ferobrite warning notice, a notice of the launch of Mitutoyos Smart Factory solutions website, a fold-out manual with 11 languages, a small notice to wipe excess oil from the calipers, a China RoHS compliance certificate (helping them to Import into China), a reminder to recycle batteries for the EU (in 7 languages) ---and--- an SR44SW battery made by Saizaiken, Japan. Batteries last a very long time in a real Mitutoyo and, just to be sure this is not a counterfeit, I made some measurements: Current when on was pulsing 2 to 6 μA and when off dropped to a stable 0.5 μA: very good. When a Mitutoyo wants a fresh battery a B is seen in the upper-right corner of the display. I measured this threshold at about 1.40 Volts. If you dont heed that warning, a Mitutoyo will not give bad or unstable readings but will instead simply turn off. I measured this cutoff threshold at 1.3 Volts and the readings were dead-stable up the that point. Other things that tend to indicate this is authentic is a CE mark with compliant dimensions, surface finish marks that are parallel with the tool, ABSOLUTE molded into the battery cover and gold plated battery contacts.

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

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.

This was a gift for my daughter for her Graduation from Engineering School, and Im sure shell be using it her entire life, like Im using still my grandfathers vernier Mitutoyo that he brought home from WW2.

This caliper is well worth the money. I had some other brands, but they never last. You can not go wrong with Mitutoyo.

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.

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.

Please note that this product review is for both: the digital caliper and the company producing them (Mitutoyo). In my opinion, a good review should take into account both facets when determining a products overall price/performance. With that said: SUMMARY In summation, this digital caliper from Mitutoyo works great as advertised BUT the shortcomings in the calipers functionality and the companys performance leads me to rate this product just three-stars. As a discerning customer who is spending $$$, I EXPECT a little more from a well-established company like Mitutoyo. Here is why: PRODUCT REVIEW The caliper (Mitutoyo 500-196-30 Advanced Onsite Sensor Absolute Scale Digital Caliper, 0-6 Range) is a wonderful device that works great. Ive used it to measure the dimensions of various KNOWN objects and I found it to be fairly accurate. For example, comparing the known dimensions of an iPhone 5 against the calipers readings, I found the measurements to be pretty exact; my measurements varied only slightly (+/- .01-.02mm), as expected. To achieve consistent readings, I had to ensure I applied the SAME continuous force for both: taking measurements and when setting the origin. Using the same amount of force I was able to achieve fairly consistent and accurate results as mentioned above. However, there IS a significant shortcoming or two from my experience. The first has to do with the lack of an auto-off feature; this digital caliper from Mitutoyo has none. Once you turn on this digital caliper, you MUST remember to turn it off or else the battery will continuously drain until you do so. In addition (but not as important) the caliper requires a battery, an (SR44SW), that is not commonly available locally in most areas. If Mitutoyos engineers decided on a more common battery like a (2023) ,the overall design would have been superior. Due to these shortcoming, the calipers rating was reduced one star lower. Overall, the caliper is great at taking consistent accurate measurements but you should already expect that given the price $$$ you are paying for this device; its not exactly inexpensive. COMPANY REVIEW In my opinion, the only technical reason for excluding such a BASIC feature as auto-off in this day-and-age is purely a Marketing technique to create product differentiation. This type of practice allows companies to create additional versions of the same exact product by varying features across their product line. This practice attempts to sway more customers towards EVEN more expensive versions of their product line and this is type of general practice is one I dont agree with. Why cant Mitutoyo just make a SINGLE highly accurate version of their caliper (one digital and one analog) that works for ALL their discerning customers (designers, engineers, hobbyist, students, etc)? Mitutoyo lists 27 different calipers on their corporate website.

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.
