Best Vernier Caliper Reviews

Vernier caliper is a type of caliper that makes use of the vernier scale to measure length, width, outside diameter, inside diameter, depth, and step. This vernier scale enables you to read in a resolution of 0.001″/0.02mm. It is commonly designed for a maximum measuring range of 6″ range. But you can also find the longer ranges such as 8″, 12″, 16″, etc.

Keep in mind that there are other 2 types of calipers that you can commonly find on the market to measure the same things: dial caliper and digital caliper.

One big advantage of using a vernier caliper is no battery needed to use it. You can take and use it every time you want without thinking of its battery. Besides, it’s relatively cheaper (not useless) compared to the dial and digital calipers. There is no LCD display. The reading is presented by calculating the main scale and the vernier scale.

This precision dimensional measuring instrument is used in many areas such as metalworking, woodworking, manufacturing, workshop, school, automotive, etc.

The best vernier caliper would at least have high accuracy, integrated construction, durable material, and clear to read the reading. If you are going to buy this instrument, perhaps, one of our top 10 vernier calipers below meet your requirements.

Things to Consider Buying A Vernier Caliper

1. Resolution

Commonly, you will find vernier calipers on the market graduated in 0.001″ (0.0254 mm). If you get the lower one, you should expect a lower price. If you need a more accurate one than 0.001″, you may need a digital caliper such as Mitutoyo 500-196-30 that has 0.0005″ resolution and ±o.001″ accuracy.

2. Accuracy

Accuracy is one of the most important things in precision measuring instruments. It doesn’t necessarily mean if your caliper has great resolution, it has great accuracy. Keep in mind that resolution is the smallest reading that it can show, while accuracy is how close you are to the truth.

If your caliper’s resolution is 0.001″ and its accuracy is 0.001″, then it’s what you have to expect. In most cases, measuring instruments’ accuracy is similar to its resolution.  However, on the other hand, if your caliper’s resolution is 0.001″ and the accuracy is 0.05″, you have to less consider this option.

3. Certificate Calibration & NIST Traceability

If you want proof that your vernier caliper is accurate as described in its specification, you need to calibrate it using a reliable calibration procedure. In this case, you could hire a vernier caliper calibration service that is ISO 17025 accredited. The result of calibration is documentation that is called certificate calibration.

When you rely on ISO 17o25 accredited calibration service, your vernier caliper will be calibrated using a standard that is traceable to NIST. Herewith, your caliper will be NIST traceable eventually. The definition of the 1-inch measurement results generated by your caliper will be the same as the other 1-inch measurements across the globe. Finally, this NIST traceability makes up how reliable your measuring tool is.

4. Material

Is it constructed with steel, stainless steel, or hardened stainless steel? You are better off choosing the stainless one rather than the steel. The stainless steel is corrosion-resistant except for the low grades. It’s hard to know the material quality. Many companies only explain the material without further description of what stainless steel grade they are using. To solve this, you could read the customer reviews whether the caliper is easy to corrode or not.

5. Integrated Body

A high-quality vernier caliper will have the sliding jaws and scale face integrated as a single body. This construction design is meant for accuracy. The lower-quality construction uses screws to hold the scale on the sliding jaws.

When the screws are the joiner, the chance of play when you shake is real. This even, eventually, generates inaccurate measurement. The most common and easiest case is when you zero the caliper. Even though both the external and the internal jaws have clamped each other, you don’t see it shows zero reading.

6. Visibility

Visibility is important in vernier caliper because we take the reading manually. The chance of parallax error is high.

You have to get the scale that is etched rather than printed. The etched scale will last longer and not easily fade out compared to the printed one.

In addition to the visibility, you have to consider the numbers’ size. Some people that have poor vision may hard to see the numbers.

7. Inch or Millimeter (Imperial or Metric)

You cannot find all of the vernier calipers on the market with both inch (imperial) and millimeter (metric) unit reading on their scale. Some of them come either in inch or mm. Thus, you have to give a little care when selecting them. Further, this variation determines the price.

How to Use Vernier Caliper with Fine Adjustment

Conclusion

So far, the best vernier caliper brand is still Mitutoyo. They have various models you could choose from. The second brand is Starrett. And the third is Fowler.

People’s preferences may differ from each other. Some people demand accuracy, while others demand low-budget caliper for general purposes. In some cases, a fractional vernier caliper is a great option for woodworking. A short-range caliper will fit in the pocket and allow high mobility. Those requirements make us enlist the top 10 vernier calipers above as choices. Eventually, you are the one that determines.

However, if you still don’t have any requirements for what to buy first, you could buy Fowler 52-057-004 (inch graduation) or Mitutoyo 530-101 (mm graduation). Those two products are low-budget models but of great quality. If you know what you want, you should look for the most excellent vernier caliper. It is Mitutoyo 532-119 as we enlist the first position. Sometimes, a product comes without a description of its accuracy, in this case, you could assess it with a gauge block or caliper checker.

As you could read thoroughly here, the majority of vernier calipers have a 0.001″ or 0.02 mm resolution. If your project requires more accuracy than that value, you may need a micrometer.
