Types of Diameter Measuring Tools

Inside Diameter Gauges

Inside diameter gauges are specifically designed to measure the inner diameters of tubes, pipes, and other cylindrical objects. They often have a set of adjustable arms that expand to fit the inner walls, allowing for accurate measurements.

Outside Diameter Gauges

Outside diameter gauges measure the outer diameter of cylindrical objects. These tools are crucial in ensuring that components fit together correctly in assembly processes.

Digital Calipers

Digital calipers provide an easy-to-read digital display, making them user-friendly for quick measurements. They can be used for both internal and external measurements, making them versatile.

Laser Diameter Gauges

Laser diameter gauges offer a non-contact measuring method, which is beneficial for fragile or moving objects. This technology uses laser beams to calculate diameters accurately without physical contact.

Micrometers

Micrometers are precision tools used to measure small dimensions, including diameters. They are available in various types, including outside, inside, and depth micrometers, each serving a specific purpose.

Specialty Diameter Gauges

Specialty diameter gauges are tailored for unique applications, such as measuring large or irregularly shaped objects. These gauges can be customized to meet specific industry requirements.
