This DC Recording Timer by IEC is a simple, low cost velocity measuring device that permits a long narrow strip of paper tape, dragged by a moving object, to pass under a carbon paper disc and a vibrating hammer which makes dots on the paper strip. The rate of hammering and the distance between the dots permits velocity to be calculated.
The heavy base and the rubber feet makes the timer stable on the table and clamps are not required. The extension rod allows the timer to be held vertically by a retort stand and the knob at the end is for safety by stopping the timer from falling through the support clamp if it becomes loose.
The kit consists of:
• 1 pce. Recording timer, with hammer and platform
• 1 roll/30m White paper tape PA2670-005
• 1 pack/25 Carbon paper discs. PA2670-007
