  "term": "Mercury-in-steel thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of thermometer that measures temperature by the expansion and contraction of mercury contained within a steel bulb and capillary tube. The change in volume of the mercury exerts pressure on a Bourdon tube, which is connected to a pointer on a calibrated scale. These instruments are known for their accuracy and durability in industrial and meteorological applications, often used for recording maximum and minimum temperatures.",
