Translation guide
A manometer is a device for measuring pressure, especially gas or liquid pressure. In Japanese, the most common equivalent is 圧力計 (atsuryokukei), but more specific terms exist depending on the type and application.
A device for measuring pressure of gases or liquids, often in industrial or laboratory settings.
General term for pressure gauge, including manometers. Widely understood and used in technical contexts.
This pressure gauge is broken.
Direct loanword from English. Used in scientific and engineering contexts, but less common than 圧力計 in everyday technical Japanese.
Measure the pressure with a manometer.
A simple manometer consisting of a U-shaped tube partially filled with liquid, used to measure pressure differences.
Specifically refers to a U-tube manometer. Common in physics and engineering education.
Measure differential pressure with a U-tube manometer.
Liquid column pressure gauge; a more formal term for manometers that use a liquid column, including U-tube types.
A device for measuring blood pressure, commonly used in medical settings.
Standard term for blood pressure monitor. While technically a type of manometer, in Japanese it is almost always called 血圧計.
Measure blood pressure with a sphygmomanometer.
Loanword for sphygmomanometer. Rarely used outside highly technical medical literature; 血圧計 is strongly preferred.
A sphygmomanometer is used in medical settings.
For most general purposes, 圧力計 is the safest choice. If you are specifically talking about a U-tube manometer in a lab, U字管マノメーター is clearer. In medical contexts, always use 血圧計 for blood pressure devices.
Liquid column manometers use mercury or water.
