What is another word for katharometer?
Pronunciation: [kˌaθɐɹˈɒmɪtə] (IPA) 
A katharometer is an instrument used to determine the vacuum inside a chamber. However, there are several other synonyms for the term. These include vacuum gauge, vacuum meter, Pirani gauge, and ionization gauge. While a katharometer uses the thermal conductivity principle to measure vacuum pressure, a Pirani gauge uses the thermal conductivity of gases in the chamber to determine pressure. An ionization gauge, on the other hand, uses ionized gas to measure pressure. Both a vacuum gauge and vacuum meter measure the level of vacuum in a chamber or vessel. Knowing these synonyms can be helpful when researching or selecting the appropriate device for a specific application.
