Yeah, that's seriously amazing. And their high accuracy mic is graduated at 0.1 um with a 0.5 um accuracy! I used to work a with near infrared lasers (something like 1.5 um). Being able to measure a fraction of that distance without optics or piezoelectrics blows my mind. Apparently they "just" added a rotary encoder to the mic XD
Neat! But anything about 101-116? I am getting nervous that I didn't buy a real Mitutoyo DX
My guess is that is a model that was specific to markets where metric is common, so doesn’t show up on the North American websites since we have the 103 series sold here in metric. The counterfeits are usually the digital products, so you are probably safe. When it arrives, take a look at the branding and compare that to what you see on the Mitutoyo website to see if there are any differences. If there is a QR code, scan that and see what it comes up with, that might be an indication on its authenticity. You can also contact Mitutoyo and have them verify the serial number.
