What's the difference between measurement and control, and why use them?
Do you need to measure or control your product?

A measurement is a precise assessment of the magnitude of an element, by comparison with a magnitude of the same type taken as a reference unit. There are a large number of possible measurements, such as :

• distance ;

• pressure ;

• mass ;

• flow ;

• intensity ;

• STRENGTH;

• etc.

This is data that can be quantified according to a standard.

Control, on the other hand, validates compliance with the specification, giving a "good" or "bad" result within certain limits. It is rarely quantifiable, but it does provide directly interpretable data on the product's technical value.
