käsimõõturid

Käsimõõturid, also known as hand calipers, are measuring instruments used for determining dimensions such as external and internal diameters, thicknesses, and depths of objects. They are typically operated by hand and consist of two arms that can be adjusted to fit around or within the object being measured. The measurement is then read from a scale, often a vernier scale or a digital display.

There are several types of käsimõõturid, including outside calipers, inside calipers, and hermaphrodite calipers. Outside calipers are used to measure external dimensions, with the arms curving outwards. Inside calipers are used for internal measurements, with arms curving inwards. Hermaphrodite calipers, also known as odd-leg calipers, have one straight leg and one curved leg, making them useful for marking off distances from edges or scribing circles.

The accuracy of käsimõõturid can vary depending on their design and the quality of their manufacture. Vernier calipers offer higher precision than simple wing calipers. Digital calipers provide the most straightforward and often the most accurate readings, eliminating the need for interpreting scales.

Käsimõõturid are widely used in various fields, including metalworking, woodworking, engineering, and machining, for tasks requiring precise measurements. They are essential tools for ensuring that parts fit together correctly and meet specified tolerances. Regular calibration and proper care are necessary to maintain their accuracy and longevity.
