What Is an Inside Caliper?
An inside caliper is a specialized tool designed to measure the internal diameter of holes or pipes. They feature jaws specifically tailored for accessing and measuring the insides of objects, often with the ability to reach into deep spaces. These calipers can provide readings in fine increments, enhancing precision in measurement tasks.
Uses of Inside Calipers
Widely used in industrial production, quality assurance labs, and research and development, inside calipers are crucial for accurately measuring internal dimensions. They are particularly valuable for tasks like checking the diameter of pipes or holes, where accurate internal measurements are essential.
Principle of Inside Calipers
Inside calipers function similarly to general calipers but are specifically designed for internal measurements. Analog types often use a vernier scale for precise readings, while digital models display measurements directly on a screen. The measuring process involves aligning the jaws with the internal sides of the object and reading the distance between them.

Errors Induced by Calipers
While user-friendly, inside calipers can be susceptible to measurement errors. These errors include zero point error, where the base measurement is not set to zero, and pitching and yawing errors due to incorrect positioning of the calipers during measurement. Additionally, excessive measuring pressure can lead to inaccurate readings, and the device might not accurately measure objects with small inner radius curvatures. In such cases, alternative measurement tools may be required.
