1546 Strobotac Digital Stroboscope RPM Tachometer features a large, five-digit LED readout that automatically displays the flash rate in bold, easy-to-read digits. This display eliminates the need to calibrate and read a dial to obtain accurate speed measurements. The 1546 emits a high intensity, short duration fl ash of light for crisp, clear images of fast moving objects. It has a broad flash frequency range from 100 to 25,000 flashes per minute.

• For machine maintenance

• Real time inspection of moving parts

• Printing press applications

• Motor troubleshooting

• For stopping motion

• Quartz crystal accuracy of ± 0.01% for
  speed, turns, or rpm measurements

• Large five-digit LED readout for instant,
  accurate readings

• Flash rates ranging from 100 to 25,000 fpm in
  three ranges

• Input connector for external triggering

The 1546 is capable of both internally and externally triggered modes of operation. In the internal mode, the flash is triggered by an internal oscillator pulse that can also drive other Strobotac
stroboscopes for additional light sources. In the external mode, the 1546 operates as a digital tachometer when a voltage pulse or contact closure is activated by the rotation of an object.
