digital counter

The Digital Counter is a timer for measuring a number of factors during an experiment: the duration of motion, transition times, periods, pendulum periods and frequencies, as well as for counting events or Geiger tube pulses.

This product includes a speaker that can be turned on and off, as well as power supplies for a direct connection to light barriers, or for powering a Geiger-Müller counter. For event counting, a fixed counting period can be programmed in a range from 1 - 99999s. Counter events (start, stop) can either be triggered by a signal to the input sockets or manually via switches.

The Digital Counter comes complete with a plug-in power supply, ready for use.
