Dial calipers are essential tools for precision measurements, offering an alternative to the Vernier mechanism. They allow readings of fractions of a millimeter or an inch through a simpler dial system. This article explores the use of internal calipers, including economy electronic inside hole calipers, Mitutoyo dial bore gauge sets, and more.
To measure the center-to-center distance between two holes, these gauges can be installed on the jaws of electronic, dial, and vernier calipers. Using a dial caliper involves adding readings from both the main scale and the dial scale. Mitutoyo, known for its comprehensive range of calibration services, operates a fully UKAS-accredited laboratory in Coventry, equipped for various precision measurements.
The dial caliper, capable of measuring internal, external, and depth dimensions, is regarded as the most versatile hand tool in the market. For zero calibration, the bezel clamp screw can be loosened, allowing the bezel to rotate to the “0” position. Caliper Range Extenders further enhance the functionality of electronic, dial, and vernier calipers for larger items.
There are those who prefer dial calipers or analog measurement equipment, often due to distrust in electronics or familiarity with analog methods. For such individuals, especially reloaders, dial calipers represent the best choice for reliability and precision. Understanding the difference between reading vernier, dial, and digital calipers is crucial for accurate measurements.
Digital Calipers, using linear encoders, offer another approach for measuring internal and external distances. The choice between digital, dial, and vernier calipers often depends on the user’s comfort and the task at hand.
