Stroboscopes
Stroboscopes

Stroboscopes are an excellent tool to freeze motion to examine moving components. Inspect production lines, couplings, shafts and belts and measure rotational speed. Phase adjust makes it possible to rotate the view once frozen. Multiply/divide allows you to quickly check you are not accidentally detecting a multiple of speed.
CAUTION: Strobes can be very convincing - inexperienced staff can forget that the motion has NOT actually stopped. We have heard of numerous near misses where junior staff were tempted to touch rotating machinery.
