This timer works like a clock and produces precisely sixty dots per second on a moving strip of paper. Calculate acceleration, drag, and friction by measuring the interval between dots. 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. Carbon discs, a 5'10" cord with on/off switch, and instructions are included. Tape is required, sold separately. Not available in Canada. Size: 7L x 2W x 1 1/4H".
