Known for their accuracy, reliability, and durability, Mitutoyo calipers are trusted by professionals across various industries for precise measurements of length, width, depth, and internal dimensions.

In this comprehensive guide, we’ll explore everything you need to know about Mitutoyo Calipers, including their types, features, how to use them, and why they are regarded as some of the best calipers available on the market.

What Are Mitutoyo Calipers?
Mitutoyo Calipers are high-precision measurement tools used to measure the dimensions of objects with high accuracy. They are an essential tool in industries like manufacturing, machining, and metalworking, as well as for scientific applications that require precise measurements.

Mitutoyo is a Japanese company that has earned a stellar reputation in the field of precision measurement tools. They produce a wide range of measuring instruments, including digital calipers, vernier calipers, and dial calipers. Mitutoyo calipers are known for their rugged construction, fine tolerances, and ease of use.

Types of Mitutoyo Calipers
Mitutoyo offers several different types of calipers to meet the varied needs of professionals. Each type has its unique features, and understanding these differences is key to selecting the right caliper for your work.

1. Vernier Calipers
Vernier calipers are the traditional type of calipers, offering a high level of precision using a scale and a sliding component. They consist of a main scale and a sliding Vernier scale, which enables users to read measurements with great accuracy.

Key Features:
Manual operation: The user reads the measurement directly from the scales, offering a more hands-on experience.
Accuracy: Mitutoyo’s Vernier calipers can measure with an accuracy of up to 0.02mm (or 0.001 inches).
Durability: Known for being robust, these calipers are built to withstand heavy use in industrial environments.
While Vernier calipers require some skill to read accurately, they are favored by many for their simplicity and ability to perform precise measurements.

2. Digital Calipers
Digital calipers offer the advantage of easy-to-read digital displays, making them a popular choice in modern workplaces. Mitutoyo digital calipers provide highly accurate measurements with the convenience of digital reading.

Key Features:

Easy-to-read digital display: Measurements are shown in an easy-to-read LCD display, eliminating the need to interpret scales.
Higher precision: Mitutoyo digital calipers often offer a precision of 0.01mm (or 0.0005 inches).
Multiple measurement modes: Digital calipers typically allow measurements in both metric and imperial units and can switch between internal, external, depth, and step measurements with ease.
Data output capabilities: Many digital calipers allow for data output to computers or printers, making them ideal for use in environments that require consistent documentation of measurements.
While digital calipers may require batteries, their ease of use and convenience make them a favorite among professionals who prioritize accuracy and speed.

3. Dial Calipers
Dial calipers feature a dial gauge for displaying measurements. Like digital calipers, dial calipers provide an easy way to read measurements, but instead of a digital screen, they use a mechanical dial that rotates to display the measurement.

Key Features:
Mechanical dial display: This caliper uses a rotating dial gauge to display measurements.
Accuracy: Mitutoyo dial calipers offer high precision, often up to 0.02mm.
Durability: Just like Vernier calipers, dial calipers are built to be sturdy and reliable, often being resistant to wear and corrosion.
Dial calipers can offer a middle ground between Vernier and digital calipers, offering easy reading without the need for batteries.

4. Depth Gage Calipers
Mitutoyo also offers specialized calipers, such as the depth gage calipers, which are specifically designed for measuring the depth of holes, grooves, and other recesses.

Key Features:
Long depth rod: Designed to measure the depth of holes or recesses with a long, adjustable probe.
Accuracy: Depth gage calipers offer precision similar to standard Mitutoyo calipers.
Ease of use: The depth gauge allows for precise measurements of internal dimensions, which can be difficult to measure with standard calipers.
Key Features of Mitutoyo Calipers
While there are various types of Mitutoyo calipers, there are several common features that set them apart and make them favorites among professionals.

1. Precision and Accuracy
Mitutoyo is known for its exceptional precision. Depending on the type of caliper, the accuracy can be as fine as 0.01mm for digital calipers or 0.02mm for Vernier and dial calipers. This level of precision makes Mitutoyo calipers ideal for tasks where even the smallest variations in measurement can have significant impacts.

2. High-Quality Materials
Mitutoyo calipers are built to last. They are typically made from stainless steel or hardened steel, ensuring both durability and corrosion resistance. Many models also feature ceramic-coated jaws that resist wear and tear from frequent use, making them ideal for environments with high precision needs.

3. User-Friendly Design
Mitutoyo calipers are designed with user comfort and ease of use in mind. The handles and thumbscrews are ergonomically designed for easy grip and smooth operation. Whether you’re using a Vernier, digital, or dial caliper, the tool is crafted to be easy to manipulate and read, ensuring accurate measurements every time.

4. Advanced Display (For Digital Calipers)
Mitutoyo’s digital calipers are equipped with LCD displays that show measurements in millimeters (mm) or inches (in). Some models have advanced features like zero-setting at any point along the scale, allowing you to subtract measurements from the current reading, as well as the ability to hold or lock the measurement for easy reading.

5. Calibration and Accuracy Checks
Mitutoyo calipers often come with calibration certificates, ensuring that each tool is accurate out of the box. They are also designed to be easily recalibrated using calibration blocks or through periodic checks.

How to Use Mitutoyo Calipers
Using Mitutoyo calipers is relatively simple, but it requires precision and a steady hand. Here’s how you can use each type effectively:

1. Using Vernier Calipers
Slide the Vernier scale along the main scale until the jaws grip the object you are measuring.
Look at the markings on both the main scale and the Vernier scale to determine the measurement.
Add the values from the main scale and the Vernier scale together to get the precise measurement.
2. Using Digital Calipers
Turn on the calipers and set them to zero.
Slide the jaws of the caliper to measure the object.
Read the measurement from the digital display in either millimeters or inches.
Switch between internal and external measurements using the appropriate buttons on the caliper.
3. Using Dial Calipers
Slide the caliper jaws to measure the object.
Read the main scale to get the initial measurement, then read the dial gauge for additional precision.
Combine the two readings to get the total measurement.
4. Using Depth Gage Calipers
Extend the depth rod and place the caliper inside the hole or groove.
Slide the caliper until the rod touches the bottom of the recess, then lock the measurement in place.
Read the measurement from the display or dial.
