  • Highly Accurate
  • Four-way measurement
  • Wide Measurements

No matter if you’re a student who’s involved in renovation projects or a mechanical engineer working on your project, you know that some works demand highly accurate measurements. In this post we will be discussing about best digital caliper.

You cannot afford to make mistake in measurements otherwise fittings of your components will not be accurate and this could hamper the success of your project. Hence we use calipers.

Taking measurements is one of the most important parts of any project, whether it involves cutting by hand, using a CNC machine , or 3D printing a model. 

Getting an accurate measurement, though, can be difficult, especially when every detail counts. Sometimes, a standard ruler or tape measure just doesn’t cut it. Hence we use calipers.

Calipers have been around for centuries and considered to be the most accurate measuring tools. They have been used in many fields such as mechanical engineering, metalworking, forestry, woodworking, science and medicine.

You can find different types of calipers like vernier calipers, dial calipers, electric calipers and more lately digital calipers.

Digital caliper has various advantages over analog calipers which help them to make precise measurements. Hence we have compiled a list to help you make the right choice.

Buying Guide to Choose the Best Digital Calipers

You should learn everything about the product as an individual before purchasing it. So in order to provide these vital details for the digital calculator we provided a guide for buying.

The following guide will show you the way to identify the best digital calibration devices and select the right choice from the list. Let us talk about the important considerations when purchasing a digital caliper.

Things to consider before buying the best digital calipers

Digital caliper has multiple components that help their overall function and design.

They contain two measuring jaws, one inside and outside jaws to measure inside and outside diameters, a depth gauge.

An LCD screen display that shows the measurements on a digital screen, the main scale that shows the measuring range, and a knurled thumb roller that moves the jaws up and down the scale.

Digital caliper uses a digital display to provide small resolutions, meaning that you can achieve more precise measurements than with a ruler (or a similar non-digital tool).

When looking at a measuring tool, like a digital caliper or micrometer, there are a few things to consider. The first and perhaps most important consideration is the tool’s accuracy, or the tolerance at which a tool can take a measurement (e.g. ±0.01 mm). The lower this value is, the better!

Each of these components has attributes that affect its function, so when looking for the best digital caliper for your specific needs, understanding these elements and how they work can help you decide to make the best choice.

Accurate Measurements

One of the important benefits of digital caliper is it’s ability to make extremely precise measurements. Digital caliper measures in increments of as small as 0.01 inches or 0.0005 inches, depending on the quality of the caliper. The electronic digital caliper components that measure the distance between the measuring jaws have the greatest influence on calipers’ accuracy level. 

Digital caliper is made of polished stainless steel frames which helps in smooth measuring jaw movements. By including added grip for fingers to slide, the jaws can move up and down, and a large, textured driving thumbwheel also can assist in making more easier movements. 

The overall measurement accuracy of a pair of digital caliper depends on a combination of the user’s skill and the unit’s individual features.

Material Type

Digital calipers are made of carbon fiber, durable stainless steel, or plastic, and each material has its own advantages and disadvantages. 

Stainless steel is the material most often used on high-end digital calipers. 

Stainless steel calipers are durable, liquid, oil, dust resistant and are the most highly priced.

Carbon fiber is lightweight and provides a medium durability level. Its carbon polymer fibers are as strong as steel but with lighter weight. 

But, carbon fiber isn’t as corrosion-resistant as stainless steel, and it can deteriorate more rapidly if exposed to water, dirt, or UV rays. 

With some exceptions, carbon fiber calipers are generally more affordable than stainless steel digital calipers.

Plastic calipers are often the most affordable digital calipers and are also lightweight, but they’re not as durable. 

Plastic digital calipers can be used for hobbly projects and are not recommended for professional projects.

Finally, composite calipers are a mix of plastic and carbon fiber that offer a middle ground between durability and affordability.

Depth Gauge

When you think of calipers, in all likelihood, you picture a set of measuring jaws that open and close on the upper portion of the measuring scale.

The depth gauge, the next tool, is a small rod that extends and reverse from the end of the caliper bar—used to measure the depths of holes, cavities, and more.

The highly useful depth gauge can be exceptionally fragile in low-quality calipers. If the depth gauge is of high importance for your needs, you need to ensure that it’s strong enough to withstand constant use. 

Stainless steel and carbon fiber are usually the best, whereas plastic or composite materials aren’t recommended.

Metric Units

Some users require the measuring system to use the Imperial system (inches and feet), while others need the metric system (mm and cm). 

Some measuring systems are more common around the world, but you may encounter both types. For example, various automobile makers use parts based on varied measuring systems.

Fortunately, almost all digital calipers display measurement units in both inches and millimeters.

A button on the LCD display appears to switch between both measuring systems. Standard measurements often are printed on the main scale.

Inside/Outside Caliper Jaws

The most regularly used parts of a digital caliper, the inside and outside jaws are used to make internal measurements and external measurements of any object. 

They are located on the opposite side of the calipers’ main scale, and the outside jaws are larger than the inside jaws. 

The outside jaws are used to measure the outside diameter of an object, while the inside jaws are utilized to measure the inside diameter of any particular object. 

Similar to the depth gauge, the inside and outside jaws move as you turn the thumbwheel (locking screw) until the teeth come in contact with the object.

To ensure more accurate measurements, the digital calipers should have robust, rugged measuring jaws. You need to pay special attention to the construction quality of the inside jaws.

IP54 level of Protection Certificate 

Some digital calipers are made to be used in harsh environments which are unfavorable to electronics, like outdoors or workshops. 

In case this is a priority, make sure your digital caliper offers standard IP (or ingress protection) rating. 

IP testing is done by a third-party certification process that certifies the environmental durability of electronic components.

The first number after “IP” means the item’s level of durability against solids, and the second number represents the tool’s level of moisture resistance. 

For a digital caliper, IP54 is the industry standard. The “5” means it is dust resistant, while the “4” means it is liquid-resistant to splashes of water from all directions. 

If your plan to use a digital caliper in an adverse environment, make sure you opt for calipers with an IP54 protection certificate.

Ease of Use 

Taking elaborate measurements can be difficult, so most users look for calipers that are easy to use. 

Thankfully, most of the characteristics that contribute to the accuracy, such as polished stainless steel parts and a large, textured thumbwheel, also make them easy to use. 

Many extra features also help to make the calipers easier to use, such as a large LCD display and locking screw.

Additional Caliper Features 

Along with the vital features listed above, you can look for several other added caliper features in digital calipers, that include:

  • Extra Large LCD display screen
  • The reset button, known as the “zero button,” enables the display measurement to be reset to 0
  • The locking screw helps to lock the inside and outside jaws at a required place
  • Automatic LCD display shutoff to save battery life
  • Data transfer port to upload measurements to software programs

How to use a Digital caliper?

You can choose the best digital caliper, but you need to know how to use the caliper tool. Hence we have listed some tips on reading a digital caliper.

At First, make sure you have “zero out”/reset the reading on the LCD display before taking any measurement. 

Once the display shows “0,” begin rotating the thumbwheel till the inside or outside jaws make adequate contact with the object. Hence it is a useful diameter measurement tool.

You can use the outside jaws to read the outside dimension of the object, and use the inside jaws for measuring the inside dimension.

To measure the depth of an object, utilize the depth gauge. Make sure the bottom of the digital caliper is at right angles to the object being measured and slide the thumb wheel till the point of the depth gauge reaches the bottom of the object.

Additional tips:

  • Tighten the locking screw after taking a measurement to store it. 
  • It is a must to calibrate your calipers (using a calibration gauge or professionally) once a year to guarantee accurate measurements.
  • Frequently check for signs of any damage, such as scratches, on the jaws and scale that could influence the correctness of your measurements.
