Q: ____measures air humidity:
  • A. Hygrometer
  • B. Micrometer
  • C. Thermometer
  • D. Hydrometer
Correct Answer: Option A - Instrument Uses Hygrometer It is instrument used in meteorological science to measure the humidity, or amount of water vapour in the air. Micrometer It is a device incorporating a calibrated screw widely used for accurate measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers. Thermometer It is an instrument that measures temperature.
