Buying Guide: Things to Look When Choose Digital Calipers

If you want to buy a good digital caliper for measurements, make sure you consider all the following things before making a purchase.

Accuracy and resolution

No user can compromise for accuracy and resolution when it comes to digital calipers. To get the most precise and correct measurements, make sure you check the accuracy is 3 to 4 decimal points. Not all digital calibers offer this accuracy, but most offer 0.001″/0.02mm accuracy that is important when dealing with small-sized objects. A slight difference can cause a problem. Resolution is the smallest reading that digital caliper will provide. Don’t opt for calipers that have a resolution less than 0.0005″. If you are new to digital caliper, it is advised to look for a caliper that comes fully calibrated with an absolute origin so you don’t have to set zero each time while turning off.

IP rating

Digital calipers certified with IP ratings are very important because it not increases the durability, it also improves efficiency and performance under different environmental conditions. Moisture, liquids, and dust on digital calibers can cause faulty readings. To avoid these problems digital calipers come under 3 different ratings; IP53, IP54, and IP67 making them resistant to water and dust. The caliper models that meets IP67 protection standard are the best as they can be used in harsh conditions and boosts exceptional dust and waterproof properties to operate in a high humidity environment or even be immersed underwater. It also delivers correct measurements at extremely low temperatures along with ultimate protection. So if your work involves such conditions, it is better to go for IP67 rated digital caliper.


As you can’t buy a digital caliper, again and again, it has to be durable enough to last for years by withstanding accidental falls. The best and ideal material for caliper construction is metal, most commonly stainless steel because it is easy to use, offers smooth gliding and provides resistance against water, oil, and dust. Though the steel built calipers are expensive than plastic, ABS or composite materials, it offers high durability.

Ease of use

To make measurements super-easy and quick, it is better to look out for the following features. The large LCD screen with high resolution will make reading digits trouble-free with the naked eye. Having a smooth movement of the jaw is also essential for effortless measuring. Plus, you need a locking screw for exact reading by locking the jaw at the correct position so it doesn’t slip and deliver wrong values.

Data transfer

If you are not good at keeping records on papers or don’t have time, you might want to have this feature. All you need to do is connect the USB cable provided with the digital caliper to your computer to transfer data.

How to Use a Digital Caliper?

A digital caliper is by far the easiest to read and use as it can operate in both imperial and metric measurements. A caliper can take measurements in 4 different ways. The outside jaws are used to measure the outside width, length, diameter, or thickness of an object. The inside jaws measure the internal width or diameter of a slot, groove, hole or a bore. The depth probe or rod is used to measure the groove slot or step. The beam or caliper’s bar is stationary and houses the depth probe. Caliper also features a measuring scale which is used as a visual reference when using a digital caliper as the LCD provides the full read.

To take the desired reading, use the jaws to take measurements and apply the lock to prevent surface drag if needed. The caliper will provide precise reading with maximum accuracy. For step measurement, close the caliper and make sure it is zeroed. Adjust the smaller jaws slightly to help the measurement surfaces rest on the edge. Then push the caliper into place and apply the lock for final reading. To switch over to the metric unit, press the blue button. For depth measurements, extend the probe long enough so it’s able to bottom. The added length is needed which allows the measuring surface of the beam to close against the object and gives you the final measurement.

How Do Digital Calipers Work?

Most of the digital caliber uses a capacitive sensor or encoders to record the measurements. It consists of a pattern of copper lines or track on the 2 layers of PCB strip which runs the length of the slide beam. The reading head also comprises a pattern of lines etched onto a PCB forming a variable capacitor. When the reading head is moved, changes in capacitance are detected by the head and value is calculated that is shown on the LCD screen.

Below the caliper’s scale, a wide variety of rectangular-shaped plates are present on the glass or copper strip used. The circuit board is present on the lower side of movable jaws. A grid of capacitor is created with the copper plates. When the jaw slides along the main scale, alignment, and misalignment of the rectangular plates take place causing the capacitance to change among two plates. A signal is sent to the chip within the caliper’s screen to generate the value digitally on the LCD screen.

Frequently Ask Question About Digital Calipers FAQ’s

Q.1- What is the best digital caliper?

The leader of digital calipers is the Mitutoyo 500-196-30 Digital Caliper which is distinguished by Japanese top quality and accuracy supported by a calibration certificate. The tool is made from first-class stainless steel and the jaws embrace laser machined surfaces for precise measurements. This model measures both external and internal diameter as well as the depth. All the components are merged with each other. Thus you won’t find any axial floats or backlashes while carrying out measurements. The unit features a 6-inch measuring range and comes fitted with an advanced on-site sensor that provides correct readings even when it is stained with water, oil or dirt. This option allows using caliper in harsh weather like heavy rains and at metal processing facilities that make use of coolants and oils. Smartly arranged controls ensure user convenience and quick tool adjustment.

Q.2- Is skinfold caliper accurate?

The pinch-test or skinfold test requires the use of a skinfold caliper to check the skin’s thickness on certain areas of the body. The readings or numbers are then calculated by using a formula to estimate the fat% of your body depending on gender and age. These calipers are typically more accurate and precise than the fat percentage scales but results may vary based on the skill level of the one carrying out the test and the type of caliper used. Only the subcutaneous adipose fat layer can be measured with a skinfold caliper.

Q.3- Are dial calipers more accurate than digital calipers?

In terms of battery, dial calipers are more long-lasting as they work without any battery. They are more affordable than digital calibers but the magnetic or electric field may barge in with the measurements giving false readings. Dial calipers maybe not the best options for users who have eye-sight issues. The digital caliber not only gives fast readings, but the measurements are also highly precise and accurate. It provides better resolution, easy read-out and large screen than dial calipers. Moreover, digital calibers have functional buttons that help in quick and easy measurements. The high-end models also offer data transfer to your PC.

Q.4- How do you use vernier calipers?

There are the main jaws and small jaws with the scale on calipers for measurements. Take your object and close the main jaws around it. To read the measurement you just made, find the last value on the main scale before the zero lines on the vernier scale. Then find the first line on the vernier scale that lines up perfectly with the line on the main scale and note that value, divides the value by several divisions on the vernier scale. Multiply the value by the smallest division of the main scale. Following these steps will provide an accurate diameter.

Final Verdict

The digital calipers are a handy tool for precise measurements that you can use easily in harsh conditions. They can also be paired with your PC to transfer the measurements data in a digital form and recorded into files in text format without requiring any extra software. We hope the reviews of the top 15 digital calipers that we have selected from a variety of models available on the market help you select the best one according to your needs.
