Buying Considerations of Best 12 Inch Digital Caliper

Whether you want to purchase a new digital caliper for professional or household use, there are certain things you must look out for. However, despite being familiar with the best products in the market, you might still find it hard to pick a suitable item for you.

That is why we have carefully written this buyer’s guide to help you navigate through the process of purchasing a new digital caliper for your work.

Here are a few key features you should always check for before buying a digital caliper.

Length (Size):

Before you buy a caliper, the first thing you should take into account is its size. The size of a caliper is proportional to its efficiency.

The longer the caliper, the more efficient the tool is. The length also indicates how much distance it can measure.

For basic repairs and minor upgrades, a 6-inches caliper is recommended. For complex or advanced work, larger calipers are more appropriate. The typical lengths are 6 inches, 12 inches, and 24 inches.

Depth gauge:

The depth gauge feature allows you to estimate the depth of a cavity or hole. It is one of the essential features of a caliper you should consider if crucial for your needs.

Usually, low-quality calipers have less sturdy depth gauges.


A well-calibrated caliper provides you a more accurate reading. Some instruments are already calibrated by the manufacturers, while some require manual calibration.

If you are a beginner, it is advised that you purchase the already calibrated calipers in the market.


One of the major reasons people use digital calipers is because they can take accurate measurements. Despite, there are variations in the degree of accuracy between different digital calipers.

The accuracy of a digital caliper is simply telling you how much deviation there can be in the readings. Thus, the higher the accuracy of a caliper, the less accurate the results.

Units of measurements:

The measurements units in which the readings are displayed are also essential features to consider. While most users prefer inches as their unit of measure, some other people want their results to be in the metric or the fractions unit.

If you are not sure which unit you might need later on, it is better that you choose a caliper that can display multiple units. Thus, you can be assured that they are available to you no matter the readings you need later on.

IP ratings:

If you are likely to use your digital caliper in a harsh weather condition or an unfavorable environment, you need a tool that can withstand it. The IP or Ingress Protection ratings indicate the environmental resilience of a digital caliper.

Calipers with IP54 ratings, for example, have high resistance to dust and water. Some other calipers are also resistant to oily substances, debris, and temporary submersion in liquids.


Reading the results of your measurements from an LCD screen is better than taking readings using printed markings. The former saves time and offers a higher degree of accuracy than the latter.

Also, most digital displays come with metric units, inches unit, feet, fraction conversions, etc. These additional features peculiar to digital readouts make it a better option.

Locking Screws:

The locking screws are essential parts of a digital caliper. They ensure that the caliper’s jaws are well secured and stable to provide a more accurate result.

You should make sure to purchase a digital caliper with high-quality locking screws to guarantee better accuracy.

Larger display:

Digital calipers with large LCD screens are easier and more convenient to read from. An ideal digital caliper should display its readings clearly on an LCD for a better users experience.


Digital Calipers are built with different materials such as plastic, stainless steel, or carbon fiber. Each type of material has its flaws and benefits.

Stainless steel, for example, is the most commonly used material for designing calipers. It is more robust, more durable, and resistant to corrosion, water, and debris.

Despite its pros, stainless steel digital calipers are often more expensive. Other alternatives like carbon fiber, plastic is more affordable but less durable.

Zero or Reset Button:

The zero button is used to reset the digital caliper to zero and as an on/off switch. This is a vital feature as well.

FAQs About Best 12 Inch Digital Caliper

1. How can I tell if my digital caliper is accurate or not?

To tell if your caliper is accurate or not, you have to perform an accuracy check. The easiest way to do this is to use an object with a known thickness or diameter.

Take the object and use your digital caliper to measure its thickness or diameter. The difference between the actual thickness or diameter and the results from the caliper indicates the accuracy.

This can help you know if your caliper is in good shape or not.

 2. What do I need a digital caliper for?

You can use a digital caliper to take accurate and precise measurements of the internal diameter, outer diameter, depth, and steps of an object. The readings are easy and convenient to read from the LCD screen. You cannot find these features on a vernier caliper.

 3. Is it appropriate to buy a digital caliper that has a length of more than 6 inches?

Digital Calipers with lengths more than 6 inches are often used for larger objects. Unless you intend to measure larger things with the caliper, you should go for smaller sizes like a 6-inch caliper.

4. How do I recharge my digital caliper when the battery is low?

Digital Calipers use batteries. The batteries are usually not recharged when they are drained. Instead, they are replaced because they are cheap to purchase.

5. What are calipers used for?

A caliper is a tool used to accurately measure the different dimensions of an object such as length, width, diameter, depth, etc. Calipers are used in various sectors like medical, engineering, education, research, laboratories, etc.

Some of the practical functions of calipers are listed below:

  • Students in schools use calipers to measure the inner diameter, outer diameter, and depths of different objects.
  • Calipers are used in scientific laboratories to measure metal expansion when there is a temperature rise or fall.
  • Calipers are used in the medical industry in the manufacture of medical tools and machines.
  • Manufacturers use calipers to measure both large and small parts during manufacturing processes.

 6. What are the differences between digital calipers and dial calipers?

  • Digital calipers do not have a mechanical system, unlike dial calipers. Dial calipers have a mechanical system that includes – racks and pinions.
  • Digital calipers are easier and faster to read, unlike dial calipers.
  • Most digital calipers provide their readings in mixed-unit systems, while dial calipers can either have metric or imperial units.
  • Digital calipers have better resolution and reliable accuracy than dial calipers.
  • Digital calipers are the most expensive calipers.

7. Should I buy a vernier caliper or a digital caliper?

For more accurate and precise results, it is better to buy a digital caliper. Digital calipers have better resolution and accuracy than vernier calipers. They are also faster to use and easier to read.

8. How do I use a digital caliper?

The outer diameter of the object:

  • Place the outer jaws on each side of the object.
  • Adjust the thumbwheel till the jaws are secured around the object.

The inner diameter of the object:

  • Place the inner jaws parallel to each side of the object.

Depth of the object:

  • Place the base of the digital caliper at a point perpendicular to the object being measured.
