Aerometer
An aerometer is an instrument designed to measure the density (among other parameters) of the air and some gases.[1][2]
The word aerometer (or Ärometer, from Ancient Greek ἀήρ -aer "air" and μέτρον -métron "measure, scale") refers to various types of devices for mesuring or handling of gases. The instruments designated with this name can be used to find: the density, the flow, the amount or some other parameter of the air or a determined gas.[1]
Another instrument called areometer (from Ancient Greek ἀραιός -araiós "lightness" and μέτρον -métron "measure, scale"), also known as hydrometer, used for measuring liquids density, is often confused with the term aerometer here defined.
