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 have been using cheap Chinese calipers for years. The difference between the Mitutoyo and the cheap Chinese calipers is night and day. The machine work of the Mitutoyo calipers is of a very high standard. Granted the price difference is huge, but after using the Mitutoyo calipers I can say the price difference is worth it in my case. I should have bought these years ago. Highly recommend Mitutoyo over anything else.

I used the Mitutoyo 500-196-30 150mm caliper for years as a student machine shop hand in undergrad, and now I bought my own set. Its as good as I remember. They are a small piece of perfection in your hands. It came with a Certificate of Inspection that is specific to my caliper (the certificate has the serial number matching my caliper). It shows measurement errors at 0, 50, 100, 150, and 200mm lengths, as well as 0, 2, 4 and 6 lengths. It is NIST traceable via No.683/283699-13. It is also NMIJ/AIST and PTB traceable. I dont know if this is the same as the certificate of calibration that is optional on mcmastercarr, but it is a convincing document. As noted by others, it does not have an auto-off feature. The batteries last a long time, so I dont think this is an issue. One small disappointment: I bought the Mitutoyo 050083-10 75mm depth gauge attachment (

I seen in other reviews about getting counterfeits. When you first get yours. Check YouTube videos. The counterfeits are easy to spot. Mine is legit thankfully.

This is a highly accurate tool and the best quality. Except nothing but the best. That is what you get with this item.

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.

I just purchased this thru Amazon, this is an excellent high-quality digital caliper. For those searching on eBay and elsewhere, this is the real Mitutoyo product in the original case, with the OEM 1-year warranty, and an official calibration certificate whose serial number matches the instrument. This is NOT a cheap imitation, its the original Mitutoyo product and the seller (listed as MSI-Viking Gauge) is an authorized Mitutoyo reseller. I did a lot of research on the Internet to be sure I was buying the real thing, and this is it! The differences between this caliper and the imitations are: The action is very smooth, the readings are stable and repeatable (tested with gauge blocks), the readout is four decimals for inches, two decimals for millimeters, and the construction is very solid, no wobble or shake. Plus, this caliper has an absolute scale, it always remembers the zero-point and you only have to reset it when you change the battery. The cheaper scales drift and need frequent resetting. You can make relative measurements easily (yellow button), but when you turn that feature off, it returns to the original zero without resetting. I highly recommend these calipers, the only caveat is that these are NOT auto-off, you must remember to turn them off after use. However, based on my experience with other Mitutoyo gauges and micrometers, the battery lasts a LONG time so I dont see this as a problem.

This calipers is accurate and simple to use.

Nice build sturdy and very accurate

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!

These are nice tight calipers
