Accurate time measurements from milliseconds to minutes Make precise time measurement simple and reliable in the student lab. The Millisecond Timer is an easy-to-use digital timer designed to measure time intervals from milliseconds up to 9999 seconds, making it suitable for everything from fast collisions to long-duration motion studies. With a clear 4-digit LED display and straightforward inputs, students can focus on the physics—not the electronics. Built for flexibility, the timer works with a wide range of sensors and triggering methods, allowing it to drop seamlessly into mechanics, motion, and waves experiments across multiple grade levels. Why Teachers Love the Millisecond Timer Easy, student-friendly operation: Simple connections and clear LED readout reduce setup time and student error. Highly versatile: Works across many experiments—from short, fast events to long-duration timing. Reliable triggering: Start and stop inputs respond to any change in circuit state, making timing consistent and repeatable. Auto-ranging display: Millisecond resolution for short times, then automatically adjusts for longer intervals up to 9999 s.
