A4950 is handheld LED stroboscope for a wide range of machinery maintenance applications.
Stroboscope enables to ostensibly stop rotating or generally periodic (reciprocating) motion of a machine. It allows also to find out the speed of rotation or to perform synchronized measurements without having to use reflective markers on the shaft.
The A4950 stroboscope uses three ultra-bright LEDs with optical system as a source of flashes. The instrument is equipped with a colour graphic display and 3-buttons keypad. Operation is very easy and intuitive. Two standard or rechargeable AA batteries are used for powering. The A4950 stroboscope can be used also as a tachometer by connecting an external tacho probe.
