The Rolux hand-held stroboscope is ideal for proximity rotational speed measurement of plants and machinery, as well as for observing moving parts in operation. Adjust the flash sequence so that the object appears stationary to the human eye, and you can then read the speed or frequency of movement from the LCD on the rolux. It uses xenon technology to produce extremely bright flashes at a reduced power consumption. The compact design of the rolux hand-held stroboscope and its one-hand operation give it the flexibility to be used at poorly accessible locations. The device registers speeds and oscillation frequencies during operation at poorly accessible or particularly sensitive points. It can also be used to observe fast, recurring sequences of movement. Example applications of the device include observations of fan blade deformation, the position of a toothed belt under load or separation of substances in a centrifuge. These are just a few illustrations of its huge range of uses in this field.
