What Does a Caliper Tool Measure?

A caliper tool measures the distance between two opposite sides of an object. Whether you're checking the thickness of materials, the diameter of a pipe, or the depth of a hole, calipers give you exact measurements down to fractions of a millimeter or inch. It's perfect for tasks that require accuracy, such as mechanical work, carpentry, or even jewelry making.

A caliper tool uses a pair of jaws (or caliper legs) that slide along a ruler or digital track to measure the size of an object. Here’s how it works:

• Inside measurement: The smaller caliper jaws measure the inner dimensions of an object, like the diameter of a hole or an opening. You place the jaws inside the object and expand them until they touch both sides.
• Outside measurement: The larger caliper jaws measure the outer dimensions, such as the thickness or width of an object. You slide the jaws open, place the object between them, and close them until they make contact with both sides.
• Precision depth gauge: The caliper’s depth rod extends from the end of the tool. You can use it for depth measurements of holes or recesses by placing the end of the caliper on the surface and extending the rod until it reaches the bottom.

Are Digital Calipers Better Than Analog?

Digital calipers are more accurate and easy to use than analog calipers.

With digital electronic calipers, you get an instant, clear reading on the screen—no need to squint or carefully interpret tiny scales. They also let you switch between units like inches and millimeters at the press of a button, so they’re incredibly versatile. Digital calipers save you time by providing fast, accurate measurements without guesswork.

While analog calipers are still reliable in tough conditions, most users find digital calipers more convenient and user-friendly for day-to-day use.

What Is a Vernier Scale?

A vernier scale is a smaller scale attached to the main measuring device on mechanical calipers. It contains more graduations than the main scale, allowing for more precise measurements. The Olsa Tools caliper doesn’t use a vernier scale because it is digital. Digital calipers clearly display precise measurements without the need for manual interpretation.

Do the Olsa Tools Caliper Need To Be Zeroed?

The digital caliper is absolute and remembers the zero point so you don’t need to zero it every time the power is cycled.

What’s the Difference Between a Micrometer and a Caliper?

The difference between a micrometer and a caliper lies in their precision and what they’re best used for.

Calipers are more versatile, capable of measuring the inside, outside, and depth of an object, and they offer a good level of accuracy (typically down to 0.0005 inches).

On the other hand, micrometers are designed for ultra-precise measurements, often down to 0.0001 inches, but they have more limited applications—usually just the outside dimensions of an object.

So, if you need versatility, go for a caliper. If you need extreme precision on specific measurements, a micrometer is the better choice.

What Is the Tolerance of a Digital Caliper?

The tolerance of a digital caliper is the allowable margin of error in its measurements. For most high-quality digital calipers, including our model, the tolerance is typically ±0.001 inches or ±0.02 mm. This means the caliper can measure within this degree of accuracy and is a reliable tool for precise tasks.

What Is the Caliper Graduation of the Olsa Tools Digital Caliper?

The caliper graduation of our digital caliper, also known as the distinct resolution, is the smallest increment the caliper can display. For our LCD screen calipers the graduation is 0.0005 inches or 0.01 mm. This means the caliper can display measurements with a very high level of precision.

Popular Types of Calipers

With a variety of caliper types available—each designed for specific tasks—you can find the perfect one to suit your needs. Here are the most popular types of calipers and what measurements they should be used for:

• Dial calipers: These calipers have a dial readout instead of a digital or vernier scale. The dial provides an easy-to-read analog display of the measurement, so they’re useful for quick, precise measurements without relying on electronics.
• Digital calipers: These calipers are favored for their simplicity, easily repeatable measurements, and precision. They feature an electronic digital display and allow users to instantly read measurements without the need to interpret scales. Most digital calipers can easily switch between an imperial and a metric display.
• Odd-leg calipers: Sometimes called "hermaphrodite calipers," these are used for marking out lines at a set distance from the edge of a workpiece. One leg has a pointed tip for scribing, while the other has a curved leg for running along the edge.
• Inside calipers: These calipers measure the internal dimensions of an object, such as the diameter of a hole or the inside of a tube.
• Outside calipers: Outside calipers measure the external dimensions of an object, such as the thickness or diameter of a round piece of material.
• Spring calipers: These calipers use a spring-loaded mechanism to measure the inside or outside dimensions of an object. Spring calipers are used in woodworking and metalworking for tasks that require consistent spacing or dimensioning.
• Mechanical vernier calipers: These calipers rely on a vernier scale for manual readings. Though they don’t provide digital readouts, mechanical vernier calipers are valued for their durability and reliability, especially in environments where electronics might not be ideal.
• Digital vernier calipers: Offering a modern twist on the traditional vernier caliper, digital vernier calipers come with an LED display screen for easy and precise readings. They provide the same high level of accuracy but with the added convenience of a digital display with resolution.
• Divider calipers: These are used primarily for marking or transferring measurements rather than reading them directly. Divider calipers feature two sharp legs, so they are useful in applications like drafting or scribing circles and arcs on materials.

What Is a Dual Reading Dial Caliper?

A dual reading dial caliper is a precision tool that allows you to measure in inches and millimeters. It features two distinct scales on the dial, one for each unit of measurement, so you can switch between metric and imperial readings without conversions or multiple tools. With a simple slide of the jaws, the caliper gives you accurate results, while the dial caliper dual reading screen ensures you can see both unit readings at a glance.

What Are Indirect Measuring Functions of Calipers?

Indirect functions of calipers allow you to measure dimensions that aren't directly accessible by the tool’s jaws. For example, you can use calipers to take accurate diameter measurements of a hole, measure the distance of curved surfaces, or measure the depth of a recess.
