Review on 📏 Enhanced Resolution Mitutoyo 531 128 Stainless Steel Measurements by Viterbo Dashora

Perfection! Highlighting the 53x Vernier models and their differences The Mitutoyo 530-531-532 series calipers are perfection, a tool that inspires you to work better. They are machined to very tight tolerances and have a satin finish that does not cause reflections, making their scale and numerals easy to read. All markings are engraved just below the surface, so they can stay practically forever. They slide smoothly and close effortlessly, but perfectly hold their position. The 530 series comes with a set screw to secure the measurement, while the 531 series uses a thumb lock, which some prefer, including me. That's why I have 531-128. The 532 series has an additional carriage that is connected to the main carriage for fine adjustment. They all have a vernier scale, an elegant 17th-century invention that makes dials and electronics seem fragile, clunky, and unnecessary. And if you need accuracy better than 0.02mm or 0.001 inch, you might want to consider a micrometer. But Mitutoyo's numbering system is more of a mishmash of many models to choose from. Here's what I learned: 530 - standard model with stop screw 531 - stop screw 532 - stop screw with auxiliary slide The second three digit number distinguishes between length, metric, inch or both, carbide tips or not, and standard or high precision. . I couldn't see the logic behind this number system other than that 101, 102 and 103 are all metric but not the only ones so it's a bit of an expedition to find what you need. The best source I've found is Mitutoyo's own website. Your search will be worth it. It's a wonder by any measure that tools of this quality, sophistication, and durability - another reviewer cited his prized Mitutoyo Patek Philippe caliper - are available so cheaply.
