The 1539-A Stroboscopic Light RPM Tachometer is a cost effective solution when external triggering only
is required or when high intensity light is necessary by using multiple units.
The Stroboslave stroboscopic light source satisfies the basic requirements for motion studies and
high-speed photography-it produces a bright white light at flash rates up to 25,000 per minute.
Since it contains no internal oscillator to establish the flash rate, it is an economical unit and is well suited
for use with external inputs.
