What's the difference between chronometer and chronometry?

Chronometer


Definition:

  • (n.) An instrument for measuring time; a timekeeper.
  • (n.) A portable timekeeper, with a heavy compensation balance, and usually beating half seconds; -- intended to keep time with great accuracy for use an astronomical observations, in determining longitude, etc.
  • (n.) A metronome.

Example Sentences:

  • (1) Time of induction of anesthesia and duration of sleep were measured with digital chronometer.
  • (2) The use of a digital display automatic chronometer during epicardial mapping is reported.
  • (3) It led to a flurry of experiments and the development of the marine chronometer by John Harrison .
  • (4) Also earmarked for display is a $5,000-10,000 marine chronometer, which Sinatra and his wife had engraved with “Good morning Mr President” and dedicated “Love Francis and Barbara” for his inauguration in 1981.
  • (5) One Tory thinker, Charlotte Vere, has implored "our best minds " to seek a solution to the imbalance, in the manner of the Board of Longitude, except, of course, that in 1714 they were still minus the marine chronometer and nobody preferred drowning.

Chronometry


Definition:

  • (n.) The art of measuring time; the measuring of time by periods or divisions.

Example Sentences:

  • (1) Chronometry of Achilles reflexes in 40 healthy subjects and 25 patients in the recovery period after cerebral stroke with regard to body posture showed that in normal subjects the vertical position was associated with a reduced time of the reflectory response whereas in the patients it was increased.
