It involves theoretical and practical aspects of measuring, ensuring accuracy and reliability in various industries such as automobile, manufacturing, medicine, and nanotechnology.

The ability of all measuring instruments to measure accurately and reliably is to be proved, to get meaningful results. For this, the results of measurement are to be compared with higher standards. The instruments, gauges to be used for measurement should be of known accuracy in order that the results obtained are meaningful. In order to identify the errors and rectification of errors, the instruments are compared with masters or standards. This act of comparison is known as calibration. The procedure for calibrating instruments is of two types namely (a) Primary calibration (b) Secondary calibration
