Metrology is based on the following motif. Everything that is produced and offered to the broad public has a certain amount of value attached to it. And across all industries, where the work is viable or essential, metrology and calibration services work and its utilities will be combined. It is essential for commercial and industrial service providers to be consistent in their own measurements in terms of the material value being offered to their clientele. For instance, one pound of meat blocked by the retail butcher must be consistent in providing its shoppers with the same amount of food in relation to the price being offered.
Another industrial example is this. It is a more direct example of what both metrology and calibration work entails. The production of a single fourteen carat gold ring needs to hold a specific amount of gold. By way of this example, such an amount will be taking into account the following; mass, temperature and volume. Metrology and the associated calibration helps to determine whether measured values are correct or not. To be a little more specific, note that metrology is defined as a ‘science of measurement’.
And in response to this science, calibration entails one or all of the following functions, namely documentation, design, evaluation, analysis and performance. All things combined, the possibilities are there to calculate measurement uncertainties. Three predominant categories of metrology exist; namely scientific metrology, industrial metrology and legal metrology. And you may be interested to note that legal metrology entails measuring the scales of economic transactions, security provisions and health requirements.
Calibration is a set of operations. These are all performed in accordance with definitive and documented procedures, usually carried out through the use of one or more instruments, used to detect, report, eliminate and/or correct.
