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

The Model A-2 Spark Timer delivers excellent performance in a compact, durable, and versatile design, specifically intended for physics laboratories, schools, and educational experiments.

Ideal for free-fall experiments and motion studies, this timer provides precise measurements and produces clear, easy-to-read spark marks on the recording tape.

The recording needle automatically lifts when the unit is switched off, making it easy to insert and remove the recording tape. The 10 Hz mode also provides clear results when working with relatively slow-moving dynamics carts.

A flashing LED and an audible signal indicate when the unit is operating. The adjustable discharge needle produces a double dot at each mark and a heavier double dot every 6 marks, making time intervals easier to identify.

The spark timer is ready to use and includes a self-storing power cord and one roll of thermal spark recording paper.

It operates on 110 V AC, 50/60 Hz and is equipped with a UL-compliant power cord.
