Designed for accuracy, durability, and classroom simplicity, this setup makes it easy to capture timing data for nearly any mechanics or dynamics lab. Whether you’re measuring acceleration, velocity, or collision events, this photogate system gives you the reliable, high-resolution timing data you need — no complex setup or computer interface required. Why Teachers Love the Timer and Photogates Accurate & Repeatable: Dual photogates deliver precise time measurements for motion studies with up to 0.1 millisecond resolution. Adaptable: Five timing modes (stopwatch, interval, frequency, period, count) gives teachers and students the flexibility to measure different types of motion without changing equipment or setup. Plug-and-Play Simplicity: Quick setup with clear digital display — no additional software or interface needed.
