Which digital calipers are best?
When it comes to construction, whether you’re building something professionally or working on a personal project, having precise measurements is crucial — being off by as little as a quarter-inch can throw off the entire design. Tape measures are good, but they rely on manual interpretation, which is rife with opportunities for human error. Digital calipers remove this possibility and give precise, minute measurements.
If you’re looking for quality digital calipers, Neiko Digital Caliper is a great option. It can give measurements down to millimeters and feature a bright LCD display.
What to know before you buy digital calipers
Digital calipers can be made from a variety of materials, though plastic and stainless steel are the most common.
- Plastic is good enough for occasional use but isn’t suited to long-term or professional use. It has the tendency to bend over time, making the calipers no longer accurate. It can be shockingly cheap, however.
- Stainless steel is the best, with high-grade stainless steel being the best of the best. It doesn’t bend, and it’s resistant to water and rust, so it can last for years. However, it can cost multiple times more than other models.
Otherwise known as size, span relates to the longest measurement calipers can give. Most calipers can measure up to 6 inches, though 8- and 12-inch models are also common. There are also 24-inch models, but these are rare and expensive.
Most digital calipers give their measurements in imperial and metric. Imperial measurements can be given as a decimal or a fraction, or both, while metric measurements typically go down to millimeters at the smallest. Double-check before purchasing that your prospective calipers give readings in your preferred system.
What to look for in quality digital calipers
The thumbwheel is responsible for moving the jaws of the calipers along the body, and as such, it’s important to have a thumbwheel with smooth action. If it’s choppy, halting or catches on something, your reading may no longer be precise.
Most digital calipers use LCD displays with various brightness levels and sizes. The brighter and larger the display, the easier it will be for you to read. Keep in mind that LCD displays can be hard to read in sunlight if the display isn’t bright enough. You still need some light, as few (if any) displays are backlit.
Some digital calipers are able to take differential measurements by being zeroed out at the distance of the first measurement and then taking a new reading of the change in distance.
How much you can expect to spend on digital calipers
Digital calipers cost $25-$100. Some are available for less than $25, but they aren’t as precise. Others cost more than $100, though these are only meant for professionals.
Digital calipers FAQ
What’s the difference between digital, dial and vernier calipers?
A. All three types of calipers have their pros and cons, and while they perform the same task, i.e., take a precise measurement, how they do so is different.
- Digital calipers use a complex series of electrical components to obtain a precise reading, which is typically displayable in your choice of metric or imperial. They’re the most susceptible to damage, including drops and other hard impacts, but they’re the easiest and fastest to use.
- Dial calipers are mechanical, making them more susceptible to hard impacts but strong against water. They only display in metric or imperial, never both, and the reading is displayed on its dial (hence the name), which can be difficult to read to untrained users.
- Vernier calipers are also mechanical, but they use fewer parts, making them harder to permanently damage from hard impacts. They take the longest to get a reading and don’t relay that information to as many decimal places, though they often relay it in both metric and imperial.
How long will the battery last on my digital calipers?
A. This depends on the calipers, the battery and how often you use it. Most last for at least a year, but heavy power-consuming calipers with weak batteries used regularly may only last a few months.
