Digital Timing System with Photogates

Microprocessor-controlled digital timer has eight built-in measurement modes.

This is a precision digital timer used to measure the time interval between any two events with high accuracy. The timer standard accuracy has been achieved using the 10 MHz Quartz Crystal Oscillator. It has four operating modes manual, free fall mode, timing gates mode and any other triggering start and stop. It has a built in power source for timing gates and the coil for g by free fall.
