Buyer’s Guide: How to Buy The Best Dial Caliper?

Before deciding on a specific dial caliper, you might want to know all about them to help yourself make the ideal decision. For those who want to make an informed and educated decision, here’s our buying guide for dial calipers.

 

Types of Calipers

If we boil down all the calipers into simpler definitions, we basically get three kinds of calipers. These are:

  1. Vernier Caliper
  2. Dial Caliper
  3. Digital Caliper

1. Vernier Caliper

Vernier caliper is the most durable type of caliper. This caliper is the original design. To achieve accuracy, it is important to align the scales properly. You will need to practice interpreting the readings on this type of calculator.

The vernier calipers have two scales. One runs along the top, and one runs along the bottom. The main scale is fixed, while the second vernier scale moves along the main one.

For precise measurements, the vernier scale is combined with the main one to give an exact measurement. The vernier caliper can display either imperial or metric measurements. However, some models will also show both.

2. Dial Caliper

A dial caliper is similar to the Vernier caliper, but it uses an indicator instead. You can use the dial scale for both comparative and direct measurements.

A dial caliper can be described as one of the leading clockwise tools. This caliper uses the rack and gear to work mechanically. The mechanism will rotate the dial clockwise. The measurement reading is indicated by the dial indicator pointing to a specific mark on the dial scale.

3. Digital Caliper

Digital calipers are still relatively new. While they can be costlier than a dial caliper (that is why they are so popular), many features make them easy to read and use. A digital caliper allows you to easily switch between inches or metric units.

This type of caliper has no moving parts and is more durable than a dial. This type is ideal for extremely difficult work environments.

 

Advantages of Dial Calipers

Every caliper has its own pros and cons. As this is an article dedicated to the dial calipers, we shall discuss the prowess of this tool instead of the other two.

The dial calipers have the following advantages:

  1. These calipers do not use any battery problems, so you won’t have to worry about losing power.
  2. The strength of the stainless steel construction resists rusting and makes the calipers long-lasting.
  3. There are no electronics problems, so that you can easily spot any issues with reading if there are any.
  4. It is much easier to fix than digital calipers.
  5. In one tool, you can do all the measurements: inside, outside, step and depth.
  6. The dial caliper’s resolution is identical to the vernier caliper. Still, the dial caliper’s accuracy is higher than the vernier caliper.
  7. Less difficult to read than a vernier scale because of the dial scale and the indicator.
  8. Simple to zero by turning the bezel.
  9. The digital caliper is more expensive, but the price of a dial caliper is still relatively affordable.

 

Types of Measurement in Dial Calipers

 

Fractional Dial Caliper:

In fractional dial caliper, the dials are indicated infractions (e.g., 3/3, 5/16, and 1/8). This only becomes an issue if the needle falls between two lines. First, you have to convert fractions into decimals; then calculate the distance between marks, and figure the result. That method is fine for seasoned users. But if that doesn’t appeal to you, check the numbers on your dial caliper before buying.

 

Decimal Dial Caliper:

Decimal dial calipers are much easier to use. You can read the dial numbers by reading the line closest to the needle’s left edge, called the reference line. First, divide the distance between two marks into tenths. Then, gauge it according to your measurements. It’s not necessary to convert any numbers, as they are already in decimals.

 

Things to Consider While Buying a Dial Caliper

Many dial calipers might appear practically identical to you. As a result, it can often be quite difficult to figure out which ones are the suitable for you. That’s why you need to know about certain features to figure out the perfect dial caliper.

 

Resolution

A precision measuring instrument needs to be precise. The most common resolution for a dial-caliper is 0.001”. Don’t buy a dial caliper if it doesn’t have this resolution. It’s better to buy a vernier dial caliper if you don’t particularly want a precision instrument, as it would be much less expensive. However, suppose you require a higher resolution than dial caliper. In that case, there is currently no caliper with a resolution greater than 0.001 inches. A micrometer may suit your need, as it has a much better resolution than a caliper.

 

Measurement Range

First, you must consider the dimensions of the items that you will be measuring. Most people find that a 6-inch measuring limit on the beam (the extended arm of the caliper) is sufficient to satisfy their requirements. Although you can purchase extended dial calipers, they might cost more than 6-inch calipers. The higher the measurement range, the more expensive it will be.

If you are unsure of the measuring range to choose from, go for the 6-inch range. It will be able to handle many tasks with a caliper. A dial caliper usually comes with a 6-inch measuring range.

 

Material

There are some plastic and fiberglass models, but most dial calipers are usually made from stainless steel or hardened stainless steel. Some manufacturers apply a titanium nitride coating to the sliding surface to improve wear resistance. This tin coating not only enhances the price of the tool but also prolongs its lifetime.

It is crucial to select the proper material for each part of your dial caliper. These materials should be able to resist corrosion and abrasion. At least stainless steel or hardened stainless steel should be the primary material used for its most critical parts. Plastic should be avoided unless it is used for trivial parts. A good dial caliper is usually a stainless steel dial caliper.

 

Accuracy

Accuracy is the measure of how similar the measurement results are to the standard. Most dial calipers have a resolution of 0.001 inches. This means that accuracy should be at least ±0.001 inches. Sometimes, the accuracy of a product is not clearly described. This is a reason to avoid the product for precise measurement. However, you can continue to use it. But, further calibration with a block gauge would be required from time to time.

 

Display

A clear dial display can help you get a quick reading. You may need to use the dial calibrator in less bright lights. In that case, choose a color that is clearly visible in the low light. Clear reading is possible with the help of a high-quality crystal. But a display made of this fancy crystal can be more expensive. In addition, you should ensure that the numbers aren’t too small. It should be fairly easy for you to read dial calipers from a distance.

 

Smooth Sliding

Dial calipers that slide easily offer a fabulous experience in measuring things. A high-quality dial caliper will have a smooth sliding feature. Consequently, the dial caliper is more expensive if it is smoother. This means that it will cost more money if you want this advantage.

 

Knife Edge Jaws

The knife edge contacts increase accuracy. We know that flatness and parallelism in the jaws can lead to inaccuracies. The jaws reduce the surface area that touches the piece that you are measuring. Therefore, you will get a more accurate measurement.

 

Caliper’s case

Dropping your dial caliper on something or hitting it against something can cause it to be out of alignment. Then, the calipers will require a recalibration. You may have lost an expensive tool if the dial caliper can’t be calibrated. Therefore, your dial caliper should come with a case with a custom-molded foam interior. This will ensure the tool stays put. Above all, the case should not allow the caliper to bounce around, as it could cause damage.

 

Price

The most affordable dial calipers cost between $15 and $33. You’ll be most disappointed with these models due to their inferior quality and poor cases.

The middle price range is around $34-$100. These calipers have greater tolerances, and the cases are usually more durable. Some of these can still get damaged by minor drops or impacts. The top-quality calipers are those that cost more than $100, which includes extended calipers.

To sum up, acquiring quality products will cost you money.

 

Conclusion

Calipers have been around for thousands of years and have never lost their utility. They are extremely precise due to their design. A dial caliper is essential if you take measurements frequently. They are usually affordable and can last many years with proper maintenance. They are also very easy to use. The above list makes it easier to choose the right option for your job.  In addition, our buyer’s guide will make it easier for you to decide which one to buy and give you the assurance that you made the right purchase.

FAQs

Are dial calipers more accurate than digital?

Ans: The quality of the dial calipers is a key factor in accuracy. The accuracy of a decently constructed unit with ultra smooth sliding mechanisms and high-quality gears will be impressive. But they won’t be as precise as the digital measuring tools. These will be much more accurate than any mechanical measuring device.

Are Mitutoyo calipers worth it?

Ans: Yes. Mitutoyo calipers are some of the top-rated calipers available in the market.

How accurate are dial calipers?

Ans: There may be variations in the accuracy of dial calipers. If used correctly, some models may have an accuracy of 0.01 inches above 6 inches. Dial calipers are accurate to within 0.001 inches of the same length, but not all models. To determine the accuracy of dial calipers, look at the number decimals on the dial scale. This will show you what each graduation interval is.

How does a dial caliper operate?

Ans: Dial calipers operate using a pinion mechanism and a rack. The jaws’ linear motion is conveyed to the dial indicator, which uses a rotary motion to indicate the exact measurement. On the other hand, the dial works with the gears that are inside it. The revolving movement depends on the dial.

What is an inside caliper?

Ans: This is the caliper that measures internal dimensions. This could be the diameter or length of a bolt or hole. The jaws, in this instance, face inwards (reverse jaws), as opposed to the jaws that curve inwardly. The reverse jaws of dial calipers are usually located at the opposite end to the larger jaws.

What is the most accurate caliper?

Ans: A digital caliper is usually the most accurate caliper. It measures lengths digitally and is free from human errors. However, it is more expensive than a dial caliper.

Who makes the finest dial caliper?

Ans: There are many brands that make high-quality dial calipers. Among them are Starrett, Mitutoyo, Fowler, iGaging, Anytime Tools, Shop Fox, Brown & Sharpe, etc.
