In Kalstein, science is applied in order to study the units and measures of magnitudes; it also defines the technical requirements of measurement methods and instruments.
Metrology laboratories are ranked hierarchically according to the quality of their standards. Although structures may vary from country to country, there are generally three levels:
National laboratory: is the one that owns the primary national standard and the national transfer patterns.
Intermediate Lab: Typically they are laboratories of universities, research centers and similar.
At any level, laboratories can be classified according to the nature of the measurements performed: dimensional metrology, electrical metrology, materials testing, etc.
an example of activity within these laboratories is when a volumetric flask is used. This flask is used to accurately measure a certain volume of liquid. The graduation mark surrounds the entire glass neck, making it easy to determine precisely when the liquid reaches the mark.
The correct way to measure volumes is to carry the fluid until the bottom of the meniscus is tangential to the brand. The fact that the neck of the flask is narrow is to increase accuracy, so a small change in volume results in a considerable increase in the height of the liquid.
Very precise, it is vital for the functioning of these laboratories that govern our square and very well measured world.
