Digital Timing System

Versatile digital timer for measuring velocity and acceleration

  • Time, speed and acceleration modes
  • USB for computer connection
This timer is based on microcontroller having crystal controlled time base to accurately measure the time intervals, speed and acceleration in various modes. It has built-in test function for the photogates. Least count time resolution is 0.1millisecond. It can also calculate acceleration due to gravity ‘g’. Instrument is self contained that requires no computer. USB port is provided for connecting to the computer. The system has in-bolt storage for 99 experiment readings through several modes. It can be used with Air track and trolley to comprehensively study several experiments on kinematics and dynamics. Working Voltage 9V DC adaptor.

Ordering information: The following features are available within the designated Digital Timing System modes.


a) Using single gate

b) Using two gates

c) Stop-watch - measures time between pressing start/stop button. Time

measurement up to 99 Seconds.

d) Pendulum - measures pendulum period.

e) Fence - measures 10 time values


a) One gate - Instantaneous
