Tips measure the rotational speed of shafts and other spinning objects.

Tips for flat-end surfaces are often used with pulleys and circular saws. They have a concave surface to fit flush over bumps, such as screw heads.

Tips for shafts with center hole are cone-shaped, so they’ll fit the inner diameter of different hole sizes.

Speed wheels measure the length and speed of conveyor belts, bolts of fabric, and material on spools. They have a grooved edge to fit over wire, cable, and cords.

Cordless Stroboscopes with Certificate of Calibration


Stroboscope with External Trigger Sensor	Stroboscope	Stroboscope with Non-Contact Tachometer

These stroboscopes come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They shine a bright flashing light at a moving object to make it appear slow moving. Use them to measure speed and to visually inspect belts and pulleys for signs of wear, such as cracking and fraying, without turning off the machine. They have a _1/4”-20 female threaded bushing for tripod mounting.

LED—LED stroboscopes produce a brighter, more uniform light than xenon stroboscopes. They also consume less battery power and generate less heat.
