Product Summary
The PASCO Smart Timer is among the most versatile and affordable measurement tools available to physics educators. This system includes a PASCO Smart Timer and two Photogates for measuring time, speed, acceleration, and count.
Features
- Two Photogates and one Pulley
- Calculates speed and acceleration, while recording time
- Menu-driven display with easy-to-follow flowchart instructions on the label
- Turn it on, plug in the photogates, and it’s ready to use
- The 3-section fence measures leading edge to leading edge for maximum accuracy.
- Can be used with the included 9V AC adapter or with 4 AA cell batteries.
- A switch inside the battery compartment disables the speed and acceleration modes, but continues time measurements to encourage manual calculations.
