Digital Photogate Timer System

Product Code: ME-9403A

Description

PASCO Photogates and Digital Timers are used in thousands of physics labs throughout the world because they are rugged and simple to operate. This system combines the Digital Photogate Timer with an Accessory Photogate. The Accessory Photogate plugs directly into the Photogate Timer to produce synced responses. In Pulse Mode, the Accessory Photogate measures the time it takes for an object to travel between two photogates. In Gate Mode, it measures the velocity of an object as it passes through the first photogate, and then again when it passes through the second photogate.

Compatible with these PASCO products:

  • Time-of-Flight Accessory
  • Freefall Timer
  • Laser Switch

Features

  • Powered by 4 C batteries (not included) or the 9V AC adapter (included)
  • Simply turn it on and begin collecting measurements
  • 0.1 ms resolution and 0.01% accuracy
  • Manual includes ten ready-to-use experiments
  • Timer serves as the base
  • Memory Function allows two measurements to be made in rapid succession, such as pre-collision and post-collision velocities
  • Two Photogates for measuring elapsed time between gate interferences
