👉 A pantochronometer is a device used to measure time intervals. It consists of a small pendulum, which oscillates at regular intervals, and a mechanical timer that counts down to the end of one interval. The time elapsed between two consecutive intervals is recorded by counting the number of swings on the pendulum over a period of time. This method is useful for measuring durations of events or periods of time, such as in astronomy, biology, and other fields where precise measurement of time is required
