Best Digital Calipers Reviews – 2020

Simple to use, accurate, and durable, calipers are an ancient tool that’s been around for millennia. Used in many fields from forestry to electrical engineering to medicine, calipers have been the measuring tool of choice even as technology has advanced. Nowadays, calipers aren’t just the tools of professionals, they’re also in the hands of everyday people.

How To Use A Caliper

Calipers are a necessary tool in anyone’s toolbox. Their main purpose is to measure the distance between the opposite sides of an object. Similar to a compass, the tips of the caliper adjust to fit across the ends needing to be measured. Holding the tips at the measured distance, you then take a ruler and measure the distance–at least, that’s the way the classic version of a caliper works.

Types of Calipers

Today’s calipers come in different forms and designs with price points ranging from budget to expensive. Let’s take a look at the different types available and choose the best one for the new user.

  • Inside – Manual caliper that measures the internal size of an object.
  • Outside – Manual caliper that measures the external size of an object.
  • Divider – Manual caliper used to mark out locations like a traditional compass.
  • Oddleg – Manual caliper used to create a line a set distance from the edge of an object.
  • Vernier – The most popular type of manual caliper, the Vernier has a fixed jaw and a sliding jaw that’s used to measure the object.
  • Dial – Manual caliper, similar to the Vernier, that uses a dial for accurate measurement.
  • Micrometer – Manual caliper that uses a calibrated screw rather than a sliding scale to measure an object.
  • Digital – The most popular type of caliper that replaces the analog data with digital data for accurate measurement. This is the style of caliper recommended for beginners and professionals alike and will be the focus of this buying guide.

Now that we’ve narrowed down our choice of caliper to a digital version, how do you decide which digital caliper is best for you and your needs?

Here is a buying guide to digital calipers followed by a list of the top 10 options available.

Digital Calipers Buying Guide

The fact that calipers haven’t gone out of style or been replaced by a different, more evolved tool is a testament to the engineering that took place thousands of years ago. Everything eventually goes digital and this is no different for calipers. Digital calipers are even more accurate than their manual cousins.

How do you decide whether to buy a brand name version or a generic? What separates an expensive digital caliper from a budget caliper? Let’s answer these questions and more by going deeper into the world of digital calipers.

Build Quality

Generally, you’re going to find only a few types of materials that are used to make digital calipers. These include stainless steel, carbon fiber, composite, and plastic. The price ranges of each of these materials vary greatly with plastic being the cheapest and stainless steel being the most expensive.

  • Stainless Steel – The heaviest of the digital calipers for a reason–steel is strong. They’re water, dirt, and oil resistant giving you a durable product that will last years.
  • Carbon Fiber – This material is newer to the scene than stainless steel but consistently rated among the top of the pack. They’re accurate, lightweight, but can get quite expensive.
  • Composite – A combination of materials make up these types of calipers in order to keep costs down. Composite digital calipers are an excellent mid-range choice for those that want to test out digital calipers without the investment.
  • Plastic – The cheapest of the digital calipers will be made from plastic. These are prone to breakage but still sport high accuracy.Looking at these materials, you need to weigh your options. Price, durability, and accuracy are the most important aspects of a digital caliper when considering your purchase. That being said, stainless steel is the hands-down favorite among professionals. They’re accurate to an intensely high degree. They also have a proper weighted feel in the hand of the user, they’re strong, and will last for a long time, if not forever.

Display

There are two main types of displays available on digital calipers. The first is your typical digital caliper with a display that’s readable so that you can write down the measurements that appear on the screen. The second type of display is an electronic digital caliper. These can store measurements allowing you to go hands-free when working on your project. There is a noticeable price difference between the two with electronic display screens costing slightly more due to the advanced technology.

Length

Digital calipers come in many different lengths for use in a variety of projects. The most typical lengths for the home crafter and hobbyist are 4-inch, 6-inch, 8-inch, and 12-inch. When purchasing a digital caliper, think about the sizes of objects that you’ll be measuring. This will guide you in your investment decision.

Professionals will be able to find much larger lengths for their digital calipers. They can purchase any of the aforementioned 4-inch through 12-inch digital calipers but if they want to find something larger a specialist store will be useful. Professional sizes are usually offered in 24-inch, 36-inch, and 48-inch for much larger projects.

Protection

Keeping digital calipers safe from dust, grime, oil, and water is key to their prolonged usage. You’re buying something that should last a while and want it protected. IP54 protection is enabled in many stainless steel digital calipers. IP54 allows for added protection from foreign objects that could damage or corrode your digital caliper.

Calibration

The most accurate digital calipers should be calibrated directly from the manufacturer. Not all manufacturers create products the same and some may lead to inaccurate calibration out of the box. The best brands will offer a calibration certificate from

Maintenance

When you purchase a $5,000.00 digital caliper, you should expect it to work forever and never need maintenance. Unfortunately, this isn’t true whether you own a cheap $50 caliper or the more expensive professional ones. There are three common errors and issues that digital calipers often run into and they mostly have to do with the batteries.

  1. Fixed Digits – Pop the battery out of your digital caliper and replace it after 30 seconds.
  2. Flashing or Disorderly Digits – Usually the cause of low electric voltage and can be fixed by replacing the battery.
  3. No Display – Check the battery and the battery connects for corrosion. Replace the battery if necessary.

Ease of Use

Using a digital caliper should be easy. You should be able to look at your device and know exactly how to operate the machine. The numbers should be clear to read to mark exact measurements. The jaws should slide smoothly and the digital readout should be accurate and detailed. It’s always a great idea to head to a brick and mortar store to get a feel for the different types of digital calipers and their usability.

Battery Life

Purchasing a digital caliper means you want a reliable product that will work when you need it and turn off when you don’t. Most of the digital calipers on the market have an auto shut off system to preserve battery life.

When buying your next digital caliper it’s important to take into account battery life. The cheap Chinese knock-offs can come in with a battery life of around 2 years so your budget won’t be an automatic judge of quality.

Price Point

Can you get a digital caliper that is accurate and built relatively well for under $50? Yes, but will it last forever is another question. What you pay is what you get when it comes to digital calipers. There is a reason that the best quality digital calipers are the most expensive. They’re immaculately engineered and accurate to a high degree. They’re made from the highest quality materials and are tested extensively prior to hitting the market.

Cheap Chinese knock-offs have flooded the market recently and while they work and can do what you want them to, you’re really missing out on all of the capabilities of a well made digital caliper.

Reliable Brands

Selecting a digital caliper can be a confusing proposition. How do you know which brands are the best? What manufacturing procedures do they use? If you’re investing serious money in a digital caliper, you’ll want to look at the brands that lead the industry. The top brands are listed below and are considered safe to purchase. If the brand you’re looking at is not on this list, it’s important that you perform more research before purchasing.
