Best Calipers - Buyer's Guide

Accuracy

The reason you are getting a caliper is so that you can get an accurate measurement of an object’s width, thickness, and circumference. You need to make sure that this precision is present in the caliper that you buy so that you can achieve your desired results. This is especially important for sensitive jobs where the smallest errors can lead to malfunctions or even injuries.

reliability

Once you get a reading, you should be able to reproduce it no matter how many times you measure something. This ensures that if you have to measure similar objects, the results will always be the same if they are supposed to be. This also helps you identify any flaw or deviation from what the measurement is supposed to be.

Durability

Although you are unlikely to use your caliper for any strenuous purpose, it should still be reasonably durable. If you drop it, for example, it should not bend or break easily. Re-calibration should also not be that big of a problem if the impact was not that hard, in the first place. This ensures that if you accidentally drop, bang, or step on the caliper, it will still function as intended

units

There should be a minimum of two units of measurement that your caliper comes with. If you can get more, this would be even better, as long as the measurement will remain precise. This provides you with a certain level of versatility in case one unit of measurement does not meet your needs.

extra features

If the caliper came with extra features or goodies, this will only be to your benefit. Waterproofing, for example, would allow you to measure in areas or situations where water will be involved. If the caliper also came with a depth measurement blade, a file for getting rid of burrs, a thickness gauge and more, then this would be even better.

Best Calipers - FAQs

What’s the function of a caliper?

This is a tool that is meant to measure the width, depth, diameter, or thickness of certain items for the purpose of building or molding. They provide accurate feedback on what to shave off, grind, reduce, or whittle away. A caliper is an essential tool for engineers, architects, construction workers, handymen, and hobbyists.

Which is better, a digital caliper or an analog caliper?

They both have their pros and cons. A digital caliper is easier to read and can provide more measurement features in a convenient manner. An analog caliper is typically tougher, more resistant to damage or corrosion, and can be used in practically any environment. There is also the issue of water-resistance, but both types can be waterproof to a certain extent.

What can I use my caliper for?

A caliper can be used for jobs that require a lot of precision such as pegs to slot perfectly into holes. This is common in designing complex machines, buildings, rooms, furniture, gadgets, and many more. If you only want to use it at home, it can be helpful in giving you the size of common household objects like pipes, light sockets, ventilation slots, and so on.

Do I need a waterproof digital caliper?

If you are measuring things underwater or in a situation where the caliper is bound to get wet, a waterproof quality would be highly beneficial. There are excellent digital calipers that can provide large, crystal-clear displays even when they get wet. Using a conventional, analog caliper would work too, but the chances of error go higher when using this option.
