Instant velocity and timing measurements without extra equipment Simplify motion measurement with the Beespi V Self-Contained Photogate — a compact, self-contained photogate that captures precise velocity and time data with no extra equipment. Just pass an object through the dual photogates, and the digital display instantly shows the velocity or elapsed time. Portable and easy to use, the Beespi V is perfect for studying acceleration, free fall, collisions, and basic dynamics with minimal setup. Why Teachers Love the BeeSpi V Instant Readouts: Two parallel photogates detect, measure, and display speeds of any objects that pass through, from zero to 99.99 m/s (measures in cm/s and km/h, too). Stores up to 5 measurements at a time. Self-Contained, Portable, & Easy to Use: Lightweight and battery-operated with no external interface or software required — everything is built in for quick setup in labs, demos, or field activities. Versatile Applications: Works with small cars, ramps, pendulums, projectiles, or any object that interrupts the beam.
