Our Digital Timer and Photogates uses an infra-red beam that, when broken, registers a meticulously accurate time measurement.  Students can choose from five timing modes:

  1. Stopwatch Mode:  Measures in seconds and is accurate to one hundredth (0.01) of a second from 0.01 to 59.99 seconds.  After one minute, the display switches to minutes: seconds.
  2. Interval Mode:  Uses one or two Photogates to electronically collect times from up to 3 different locations.  Photogate A, Photogate B, and/or the time between the two allowing for experiments on speed or acceleration.
  3. Frequency Mode:  Measures the frequency of anything that breaks the light beams in the Photogates regularly, or the frequency of signals applied to the inputs.
  4. Period Mode:  Measures the period of repetitive motions to 0.0001 seconds accuracy
  5. Count Mode:  Counts whenever anything breaks the light beam, or sends a signal.  There are two independent counters; each can each count up to 19,999.

Photogates are equipped with handy thumbscrews that are easy to connect and reposition.
