Mitutoyo500-197-30 Digital ABS AOS Caliper Thumb R. without Output

These are genuine mitutoyo calipers, there's not really much more to say about them. They work perfectly, they measure perfectly, the battery lasts forever and the absolute measurement means you never need to zero the calipers.Yes, these are expensive, significantly more expensive than the 150mm version but that extra 50mm over a 'standard' caliper makes a big difference - many times I've maxed out a standard caliper, the 200mm range is well worth having.Whilst cheap digital calipers are generally very good, they can be a bit hit and miss. Measurements with cheap calipers are typically very good, but they don't always run smoothly or can have points where the measurement skips, the steel isn't as hard as quality calipers and the grind of the faces isn't as good. The Mitutoyos of course exhibit none of these issues, they are incredibly smooth across the entire range, the steel is exceptional and the grinding is perfect. It doesn't matter how fast you open/close the calipers, it will never miss a step, and zero is always exactly zero.This model is not coolant proof, so not good for machinists, but they are perfect for engineers working at a desk or clean environment. Mitutoyo do of course have the coolant proof/waterproof version for use in a machine shop.

I have been using Mitutoyo callipers for over 45 years and I have become accustomed to their accuracy and reliability. This purchase was to upgrade to a digital display. The calliper is everything I expected; easy to use, clear display and spot on accuracy checked against a micrometer. A resolution of 0.01mm is better than general engineering expectations and heading well into the toolmaking world. Mitutoyo have retained four measurement types; external, internal, step and depth with knife edges on the external and internal jaws. The callipers from 40 years ago used a toothed rack as a measuring element but conversion to digital measuring system has removed this weak point making the instrument more robust and reliable. The instrument case has been upgraded and is now made from a robust plastic and able to protect the calliper when not in use.

I was a little worried about other views having received fake items, however, no issue with mine, 100% genuine. No battery in the unit (which is how they should come), genuine battery and matching code, rather than cheaper option. All paperwork is original and all code and barcodes etc. match. I use these a lot and am 100% sure this is a genuine article.Too quality product, solid build, very accurate.
