Detection Screen

Features:

1. Test the specific position of holes and light curtains, which can be used in the education industry to measure how far the long jump or shot put is thrown; It can also be used in industrial object positioning. The aluminum shell has the advantages of strong compression resistance, stable performance, easy alignment, high precision and good performance. Can be customized according to customer needs 2. The minimum accuracy can meet 1.25mm, the farthest shooting range can meet 30 meters
