METRONOME
Spring driven mechanism, adjustable from 40 to 208
beats per minute.
STOPWATCH
STOPWATCH , 0-30 minutes
With manual stop and reset. Accurarcy : 1/5 second.
STOPWATCH, 0-15 minutes
As above, but with 1/10 second accuracy.
INTERVAL; TIMER
Suiitable for all laboratory operations requiring
the timing of preset intervals ( photography, thermal and mechanical
processes, etc).The time perid may be preset for up to 2 hours wioth an
accuracy of 1/4 minute. The end of the time period is signalied by an alarm.
FIGURE
ELETTRONIC DIGITAL TIMER
This timer
was designed to replace the traditional dial type timer, and has the
advantage of lower cost and a more moder concept. The timing signal are
generated by an integrated circuit oscillator wich guarantees accuracy equal
to the sensitivity of the instrument independent of the mains frequency. It
is particulay useful with the air track 4132.00, the oscillations counter
2237.10, the free fall apparatus 4134.65, and the atwood machine 4133.00.

TIMER
This electronic digital timer permits the measurement of time
intervals with choice of 1/10, 1/100, 1/100, or 1/100 second accuracy. The
timer is activated by electromechanical gates. The tiemr operates with the
photocell gates under all room ligthting conditions. Two timing modes: q)
automatic display of time interval between successive level changes on the
same gate, or b) automatic display of time interval between level changes on
the two different gates.
PULSE COUNTER
The unit may also be used as a pulse counter with pulses between 100
mV and 50 V, with not less than 500 ms; the pulses may be supplied by a G-M
tube. A muliple socjėket on the timer supplies the G-M tube with the
necessary power.
FREQUENCY METER
the input signal, between 100 Mv and 50 V, is via a pair of
GENERAL Protection electronic and via fuses (
Power input 110-220 V, 50-60 Hz.
