Recording Spark Timer

Item# MC-TIMERSP

This AC spark recording timer is used to measure velocity and acceleration of falling or moving objects in dynamics studies. It produces sparks at uniform time intervals which are marked on a paper tape. The distance between the marks is used to calculate velocity and acceleration. It comes with 120' of recording paper tape, 5 carbon discs, a table clamp, and a 300g weight. Uses standard AC 110-volt power. Includes a study guide with instructions and experiments.

The frequency is every 1/60th or 0.0167 seconds and is not adjustable. It features an on/off button. The red and black terminals can be used to attach optional items such as an oscilloscope (not currently available through Home Science Tools). It can be used with a low-friction rolling cart for speed and acceleration experiments.

This recording spark timer uses replacement paper tape and carbon discs.

The unit is 60hz (50hz is seen in the older photo).

Great product Review by
Son was impressed with the way this recording spark timer worked. We are anxious do to more experiments with it.
Worked great for BJU Physics Review by
We have used this twice for labs in our current Bob Jones Physics course. Took a little getting used to, but once we mastered it, it did a great job, especially measuring acceleration of a cart on an inclined ramp. Really instructional to see the dots on the tape as they farther apart, indicating acceleration. Glad I bought it.
