Counter P
For counting of counter tube pulses or other
electrical pulses as well as for frequency and
time measurement. Especially suitable for student
work. With LED display and special
counter tube input with internal high-voltage
supply. Counter start, stop and reset either
internally via built-in switches or by external
switches such as, for example, contact plates
or light barriers. With built-in loudspeaker, switchable,
for acoustical pulse indication.
