noun
Technical term for an instrument that measures gas or liquid pressure; used in physics, engineering, and medical contexts.
実験ではマノメーターを使って気圧を測定した。
In the experiment, we measured the air pressure using a manometer.
圧力計 is a broader Japanese term for any pressure gauge, while マノメーター specifically refers to a manometer, often a U-tube or digital device.
Borrowed from English 'manometer', ultimately from Greek 'manos' (thin, rare) and 'metron' (measure).
