perometrie
Perométrie is a term whose meaning depends on language and field, and it is not universally used to denote a single technique. In ophthalmology, the related term périmétrie (visual field testing) is the standard concept for measuring the scope and sensitivity of a person’s vision. In electrochemistry and analytical chemistry, amperométrie (amperometry) refers to techniques that monitor current while a fixed potential is applied to an electrochemical cell. Because some sources render the word without diacritics, the term can be ambiguous without context.
Périmétrie, in the ophthalmic sense, is a functional test of the visual field. It assesses how far
Amperométrie, in electrochemistry, measures current as a function of time or potential to study redox reactions.
