This timer works like a clock and produces precisely sixty dots per second on a moving strip of paper. The unit is heavy enough to rest on the edge of a table without clamps and is also designed to clamp to an upright support rod or crossbar. The timer is powered directly by 110 V AC via a 5' 10" cord with an on/off switch.

Ordering information: Timer is supplied with 12 carbon disks and instructions. Tape is required and sold seperately. Not available in Canada.
