In the paper the velocity measurement accuracy analysis of impact testers dropping platen is shown. The measurement is carried out by two devices: accelerometer and high speed camera. During research it was assumed that dropping platen is moving in uniformly accelerated motion. The uncertainty of velocity measurement for each method was determined depending on the sampling frequency of measuring devices and the free fall height of dropping platen.
