Tachometers
Laboratory touchless tachometers measure centrifuges, pumps, rollers, shafts, gears, motors, and moving surfaces by locking on to self-adhesive tabs with a beam of light and tracking the number of revolutions. Contact tachometers measure in a similar manner, only with the rotating surface touching the tip or speed wheel of the device. Precision components ensure stable and reproducible results. The tachometers clear displays are easy to read with digital counters and low-battery indicators.
Vernier® Rotary Motion Motor Kit
This kit includes a small electric motor with pulley, rubber band belt, motor clip, and mounting screw. The motor can be attached to the Rotary Motion Sensor, and be used as an analog tachometer, or generator. You can also perform experiments that investigate motor efficiency in different conditions.
