Calipers
The Calipers category covers manual measuring tools that typically have a graduated beam with a fixed jaw and a sliding jaw, used in precision assembly and maintenance work, with available measurement functions depending on model design. Readout types include vernier, dial and digital. The fact that a caliper is digital does not necessarily make it more accurate or finer in resolution than a vernier one; both relate to the documented model specification. Specifications are model-specific.

About this category
Calipers are precision manual measuring tools consisting of a fixed graduated beam and a sliding jaw. Calipers come in different readout configurations — vernier, dial and digital — with functions, range, resolution and documented accuracy depending on instrument design. Depending on caliper design, measurement functions may include upper jaws for internal dimensions (such as hole diameters), lower jaws for external dimensions (such as shaft diameters), a depth rod at the opposite end for depth measurement, and the step faces at the end of the beam for step measurement; available functions vary by model. Models differ in measurement range (the documented span the instrument is designed to measure), resolution (the smallest displayed increment according to the instrument design) and documented accuracy (the measurement-performance specification). Available types include digital calipers with an electronic display showing the value directly, dial calipers with a rotating indicator, and traditional vernier calipers with a manual scale. The fact that a caliper is digital does not necessarily make it more accurate than a vernier one: accuracy depends on model specification and the operator's ability to read correctly. Micrometers are excluded from this category because they operate on a different measurement principle, and laser distance meters have their own category under Measurement Tools. Industrial buyers select caliper models based on required measurement range, accuracy, resolution, display type and site conditions including humidity and dirt exposure.
