The buillt-in stroboscope inside the A4900 Vibrio M is a usual tool for visual machine inspection. It utilizes High intensity LED's.
Stroboscope is very handy for inspection of rotating or moving
machinery (belt, fan, coupler...). For example, missing screw can
be seen without stopping the machine - can be a big cost saving.
A4900 can automatically detect the rotating speed of the machine and freeze
the movement by setting its flashing frequency the same as
the rotating parts. Frequency can also be set manually.
