Function and Applications

The chronometer Timer 2-1 has a 4-digit digital display and has been specially designed for use in student experiments and demonstrative teacher experiments.

Benefits

• The starting and stopping of the built-in timer piece, as well as counting, is effected by the opening and closing of electrical circuits, across light barriers or other TTL signal sources.
• Many and various experimental requirements can be fullfilled with the 4 different operating modes that the Timer 2-1 makes available for track experiments, for the measurement of the time, of revolution, of a turning movement, for the direct measurement of the period of a full swing, of a mechanical pendulum and for the counting of events
