Beta Tools – The reliable choice for precise measurement

A caliper is a measuring instrument used to measure the distance between two opposite sides of an object. There are two main types of calipers:

  • Vernier Caliper: These feature a main scale marked in millimeters or inches and a movable jaw that slides along this scale. Attached to the movable jaw is a vernier scale, which provides finer measurements by allowing interpolation between the markings on the main scale. Vernier calipers are commonly used in various fields, including machining, engineering, and science.
  • Digital Caliper: These use electronic components to provide digital readouts of measurements. While they may not incorporate a physical vernier scales, they function similarly by providing precise measurements, often to within thousandths of an inch or hundredths of a millimeter.

Both types of calipers are versatile tools for measuring the dimensionsof objects with high accuracy.

Our quality vernier calipers are designed to meet professional-grade standards, allowing for precise measurements with maximum accuracy no matter what project you’re tackling. We also have a variety of digital calipers that are convenient and reliable when it comes to taking accurate, immediate readings.

Before buying a vernier caliper or digital caliper, consider the following factors to ensure you choose the right tool for your needs:

  • Accuracy and Precision: Determine the level of precision required for your measurements. Digital calipers generally offer higher precision than vernier calipers. Consider the tolerances of your measurements and choose accordingly.
  • Ease of Use: Consider your familiarity with using calipers and your preference for reading measurements. Digital calipers provide easy-to-read digital displays, while vernier calipers require interpreting scale markings. Choose the type that you find most comfortable and convenient to use.
  • Environment: Consider the environment in which you will be using the caliper. Digital calipers may be more susceptible to damage from moisture, dust, or extreme temperatures due to their electronic components. Vernier calipers, with fewer electronic parts, may be more durable in certain environments.
  • Additional Features: Determine if you require any additional features such as data output, zero setting, or conversion between different units of measurement. Digital calipers often offer these extra features, while vernier calipers provide basic measurement capabilities.
  • Calibration and Maintenance: Consider the ease of calibration and maintenance for the caliper. Both vernier and digital calipers require periodic calibration to ensure accuracy. Ensure that you can perform calibration procedures easily and that the caliper is built to withstand regular use and maintenance.


Are digital calipers reliable?

Yes! Digital calipers offer quick and accurate readings for professionals looking to measure their projects with precision without unnecessary delays or guesswork.

Are Vernier calipers better than digital?

It really depends on the project – both types of calipers offer quick and precise measurements but choosing one over another will depend on what you’re trying to measure and your own personal preferences. 

What is a digital caliper used for?

Digital calipers are typically used for measuring linear dimensions like step distances, inlets/outlets diameters, length (inside/outside), depth as well as angles including bore angles (inclined surfaces) and their widths.
