Spark Timer Model A-2 – Compact and High-Precision

The new Spark Timer Model A-2 delivers high performance in a compact design, making it ideal for laboratories and educational experiments. Designed to operate vertically, it is perfect for free-fall experiments and precise measurements.

With a 10 Hz setting, the A-2 ensures clear, easy-to-read results, even for slow-moving carts in dynamic experiments. The recording needle automatically lifts when the timer is turned off, making it simple to insert or remove the spark recording tape.

A blinking LED and audible signal indicate the timer is operating. The fully adjustable discharge needle marks a double dot at each interval and a bold double dot every six intervals, providing accurate and easy-to-read 10 Hz markings.

Each unit comes with a self-retracting power cord and a free spark recording tape, ready for immediate use on a standard 110 V AC, 50/60 Hz power supply.
