Measuring tools

The measuring tool ( measuring tool before the spelling reform ), still referred to as a measuring tool in the calibration regulations of 1942 , is a mechanical measuring device for length and angle measurement.

Outside micrometer (reading 1.64 mm)

Digital and analog height gauge

Measuring tools belong to the group of indicating measuring devices. They have an analog or digital display as well as a defined measuring range with a defined tolerance . The essential feature here is that, in order to avoid measurement errors, the measurement is not carried out purely by hand, but by means of a measuring mechanism ( adjusting screw or linear guide ) and using various accessories and devices such as tripods or holders. One of the measuring tools include altimeters , calipers (DIN 862) micrometers (DIN 863), spirit levels(DIN 877 and 2276) as well as protractors and compasses with mechanical adjustment.

In addition to pure measurement, measuring tools are also used to check the location and position of workpieces , such as when clamping in a machine. In the past, measuring tools was also used as a generic term for all length measuring devices. A distinction was made between simple (simple measuring rods) and adjustable measuring tools. In practice, measuring tools often refer to a complete set of such measuring devices and accessories.
