Criteria for Choosing the Best Micrometres
Professionals like doctors, engineers, and contractors don’t have the luxury of making mistakes like the rest of us do, at least to some extent. Therefore, they need the best micrometers the industry can provide. It’s not enough that they are accurate. They similarly need to minimize or ideally entirely eliminate the likelihood of errors.
A user-friendly thumb roller allows for easy and quick one-hand adjustments and together with the lock screw, ensure outstanding accuracy every time. The display, on the other hand, should be high contrast and large enough to enable you to see measurements without straining.
Moist environments increase susceptibility to rust and corrosion while dust and oil can compromise the overall performance of a micrometer. Consequently, you need a micrometer forged from commercial-grade materials to provide for superior resistance to these elements as well as wear and tear. It’s for this reason that the vast majority of our picks are made from first-rate stainless steel.
The cost of a micrometer can be indicative of its overall performance and construction quality. The rule of thumb is that costly models offer superior accuracy and heart-stopping performance, though there are exceptions to this rule. Overall, micrometers are pretty affordable, rarely going for more 200 bucks.
For the value-conscious users out there who want the best bang for the buck, it’s highly recommended you invest in a high-end model. They’ll be expensive but they’ll provide you with several years of flawless, smooth, quick, and dependable service, not to mention dead-on accurate measurements in light of their exceptional engineering.
While convenience features help make quick and short work of otherwise onerous tasks, they have a way of inflating the price. Still, they’re a welcome addition for those who want hassle-free, flawless performance. Among other things, the display should be large enough to allow you to read the results with ease and the jaws need to slide effortlessly.
The thumb roll needs to be user-friendly to provide for one-handed operation. Also, consider the physical attributes. A micrometer needs to be highly portable, lightweight and compact.
Frequently Asked Questions
Q: How do I accurately measure with a micrometer?
A: For greenhorns, practice makes perfect. Make a point of firmly holding the jaws to the object you want to measure. Position the jaws in such a way it’s either square or perpendicular to the part. For the best results, ensure the jaws are free of rust, scratches, dirt, and other debris.
Q: What is the best way of storing it?
A: Other than ensuring they are super clean, apply a thin coat of oil to the jaws to stop rust and corrosion. It’s also recommended you keep it in its original box.
So here we are. Our carefully curated list showcases the crème-de-la-crème of the micrometer market. Provided you choose in accordance with the tasks you want to undertake, you can never go wrong with any of our picks. They are the epitome of fine engineering, accuracy, portability, and convenience.
