  "term": "Electrometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A sensitive instrument designed to measure electric charge or electrical potential difference, particularly very small currents. It operates by detecting the force exerted on a charged object or by measuring the voltage across a high impedance. In atmospheric science, electrometers are used to measure atmospheric electric fields and ion concentrations.",
