Product Summary
The ME-8930 Smart Timer works with all PASCO timing devices:
- Accessory Photogate
- Photogate/Pulley System
- Time-of-Flight Accessory
- Freefall Adapter
- Laser Switch
- G-M Tube
Features
- Works With 2 Photogates
- More Than Just a Timer: Calculates speed and acceleration as well as measuring time.
- Intuitive Operation: The menu-driven display mirrors the easy-to-follow flowchart on the Smart Timer label.
- Quick Setup:Turn on the switch, plug in the photogates, and it’s ready to use.
- Increased Timing Accuracy: The redesigned 3-section fence (2 included) uses more accurate method of measurement from leading edge to leading edge.
- Portable or Plug-in:The battery-operated (4 AA cells) Smart Timer can be used anywhere. It can also be operated on the 9 V AC adapter (included).
- Calculation Lock-out Switch: A switch inside the battery compartment disables the speed and acceleration modes. Timing modes are unaffected, and students are required to do their own calculations.
