Calipers are a type of measuring instrument with a high degree of accuracy and little margin for error when measuring length, diameter, thickness or distances. These measuring calipers offer features such as digital displays and vernier scales. These tools are mostly found in physics labs, machine shops and engineering applications. There are many styles of calipers, but the principle of measuring is the same.

## **Key Features of Measuring Calipers**

Explore the key attributes of measuring calipers that make them vital tools across various industries:

- **Precise Measurement:** Calipers provide precise measurements by employing a sliding scale and a locking screw mechanism, which allows for accurate alignment and stable measurement of objects across various dimensions.
- **Ease of Use:** The user-friendly design of calipers makes them accessible even for those new to technical equipment. Clear digital displays and straightforward controls enhance the ease of obtaining accurate readings.
- **Wide Measurement Range:** Calipers are adaptable tools that measure various dimensions, including internal, external, depth, and step measurements. They support both metric and imperial units, making them versatile for global applications.
- **Durability:** Their robust construction, primarily made from stainless steel, makes calipers exceptionally durable and capable of withstanding the rigours of daily use in demanding environments.
- **Portability:** The compact and lightweight nature of calipers makes them easy to carry, ensuring that precise measurements can be taken anywhere, from fieldwork to on-site adjustments in industrial settings.

## **Different Types of Caliper**

Delve into the characteristics of the different types of calipers, including electronic or digital caliper options:

### **Vernier Caliper**

Also known as vernier gauges, they are particularly useful when you need to measure something round. They feature a fixed main scale and a moving vernier scale. The main scale usually is in tenths of an inch or millimetres, while the vernier scale normally measures to the nearest 0.02 millimetres or 0.001 inches. Digital vernier calipers enhance this functionality by providing a digital display, allowing quicker and more precise measurements without the need to manually interpret the scale.

### **Dial Caliper**

These provide measurements with the same level of accuracy as Vernier calipers. However, instead of using two scales, a dial is used to read the final fraction of an inch or a millimetre on a dial. The measurement taken on a dial caliper is very easy to read.

### **Digital Caliper**

Digital calipers use linear encoders to measure internal and external distances. This is then shown on a digital display that is simple to use and read. Available with metric and imperial conversions so you can accurately measure objects with ease.

### **Spring Caliper**

The primary purpose of spring calipers is to measure the internal and external diameter of an object. They differentiate by the measuring edges and get the name “spring caliper“ by the spring joint that loads onto the nut. To adjust the size of the measuring tips, turn the adjuster clockwise or anti-clockwise. For those who prefer an easier and quicker reading, a digital spring caliper offers a clear and immediate visual representation of measurements.

## **Caliper Applications**
- **Manufacturing:** Calipers are essential in manufacturing to ensure product components meet stringent dimensional specifications. They help maintain quality control by verifying minute tolerances.
- **Construction:** Used to measure materials like pipes and wood, calipers ensure that dimensions are followed accurately, which is critical for structural integrity and project specifications.
- **Automotive Industry:** In automotive engineering, calipers measure critical parts like engine components and brake systems, ensuring vehicles meet safety and performance standards.
- **Electronics:** Calipers are used to measure the dimensions of electronic components like circuit boards and connectors, ensuring precise fits and adherence to design specifications.
- **Jewellery Making:** Calipers measure small, delicate items in jewellery making, allowing jewellers to create precise cuts and fittings that are essential for their pieces' aesthetic and functional qualities.

## **Calibration Options for Calipers**

Discover the different ways to keep your calipers accurate and reliable for all your measurement needs.

- **Self-Calibration:** This involves the user adjusting the caliper themselves, typically using a known measurement standard, such as a calibration block. This method allows users to quickly and periodically check the accuracy of their calipers, ensuring they continue to measure precisely. It's suitable for environments where calipers are frequently used and require regular verification.
- **Professional Calibration Service:** Professional calibration services are recommended for calipers that require high precision or are used in critical measurements. These services use certified equipment and methods to ensure calipers meet or exceed manufacturer specifications and international standards. Professional calibration services also include cleaning, minor repairs, and battery replacement for digital calipers.

If you're not confident in calibrating your calipers yourself, consider turning to RS HK. We offer [professional calibration services](https://hken.rs-online.com/web/content/services/calibration) for both mechanical and electronic calipers, ensuring your tools are precise and dependable.
