Timer Counter
Product Code : JA-FMDE-9433
The Timer Counter (SKU JA-FMDE-9433) is a mains-operated digital timer counter for physics lab work in schools and colleges, used to time motion experiments, count pulses and read frequency. It has a six-digit red LED display, 0.1 ms timing resolution and push-button selection of Stop/Start, PhotoGate, Period and Pendulum timing modes, with a memory for 20 readings. JaincoLab manufactures it for mechanics and dynamics practicals alongside its force and motion apparatus.
Specifications
The Timer Counter times events up to 99.9999 s at 0.1 ms (0.0001 s) resolution and then continues to 999.999 s in 1 ms steps, shows each reading with its unit on a six-digit LED display and runs from 240 V AC mains; the listed specification is summarised below.

Applications of the digital timer counter
In the physics laboratory the timer counter is used wherever a time interval, a count or a frequency has to be measured more precisely than a hand-held stopwatch allows, usually with photogates or start/stop switches connected to its input sockets.
- Timing a trolley or glider between photogates to find velocity and acceleration in force and motion practicals
- Measuring the period of a simple pendulum in Pendulum mode when determining g
- Timing free fall and other short events through the Stop/Start inputs
- Counting pulses over a fixed 1 s, 10 s or 100 s interval, or reading a frequency directly in Hz
- Averaging repeated readings from the 20-value memory to reduce timing error in class results
- College and B.Sc mechanics practicals that need 0.1 ms timing resolution
