1531-AB Stroboscope
RPM Measurement Tachometer.
These stroboscopes are small
portable flashing-light sources used to measure the
speed of fast-moving devices or to produce the optical
effort of stopping or slowing high-speed motion for
observation.
The
1531 is more economical to buy. On the other hand, the
1538 gives you six times the maximum flash rate of the
former, and portable operation is possible with a
rechargeable battery.
The 1538-A can also supports an
optional extension lamp.
Flash rates up to 150,000 flashes per minute.
