Notes on Usage

• "Áp kí" is a rare and technical term. The more common general term for a pressure gauge in Vietnamese is "áp kế" (manometer).
• It is important not to confuse "áp kí" with "áp kế". An "áp kí" specifically produces a graphical record (a chart or graph), while an "áp kế" typically only shows a pressure reading at a given moment.
