  "term": "Dew point hygrometer",
  "field": "Chemistry",
  "definition": "An instrument designed to measure the dew point temperature of a gas, thereby determining its absolute humidity. It operates by cooling a mirror surface until condensation forms, at which point the mirror's temperature is recorded. This method provides a highly accurate measurement of the water vapor content in a gas sample.",
