Mikrokator 509–4 C.E Johansson Eskilstuna Sweden. A Johansson Mikrokator (also called Abramson's movement) is a mechanical comparator used to obtain mechanical magnification of the difference in length as compared to a standard.
Producing good measurements is important in industry as it has an impact on the value and quality of the end product, and a 10–15% impact on production costs. [6] Although the emphasis in this area of metrology is on the measurements themselves, traceability of the measuring-device calibration is necessary to ensure confidence in the measurement.

Standardized measurements are essential to technological advancement, and early measurement tools have been found dating back to the dawn of human civilization. [1] Early Mesopotamian and Egyptian metrologists created a set of measurement standards based on body parts known as anthropic units. These ancient systems of measurements utilized ...
Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities.It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory.
The scope and application of measurement are dependent on the context and discipline. In natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrology published by the International Bureau of Weights and Measures. [2]
Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained.
