⚡ Spark Timer Model A-2 – Precision & High Performance in a Compact Design

The Spark Timer Model A-2 delivers high-performance timing in a compact, versatile instrument designed for physics laboratories and classroom experiments. Ideal for Falling Bodies Experiments, this timer provides precise measurements and clear, easy-to-read spark recordings.

Its recording needle lifts automatically when the timer is turned off, allowing effortless insertion or removal of the recording tape. The 10 Hz setting ensures crisp, accurate readings, even with slower-moving dynamic carts.

A blinking LED and audible signal indicate that the timer is ON. For maximum clarity, the adjustable discharge needle leaves a double dot at each point and a bold double dot at every 6th point, clearly marking the 10 Hz interval.

This unit comes ready to use, complete with a self-storing power cord and a free roll of thermal-coated spark tape. Operates on standard 110 V AC, 50/60 Hz, with a UL-compliant power cable for safety and reliability.
