Pair Of Photogates With Brackets, 2 Each

The Pair of Photogates With Brackets by United Scientific is a set of two replacement photogates with mounting brackets for United Scientific's Digital Timer with Photogates. The gates signal the timer when an object passes through, supporting interruption timing, velocity, acceleration, and free fall measurements. Physics teachers order the pair to repair an existing timer or keep a spare set for busy lab stations.
