In a ticker tape timer, the striker taps down at a steady rate, and the carbon disc between the striker and the paper tape turns each tap into a small dark dot. As a trolley or falling mass pulls the tape through, the pattern of dots becomes a record of its motion, so a clean, fresh disc is what keeps the dots sharp enough to measure.
When dots start to look faint or patchy, turn the disc slightly so the striker meets an unused area, and replace it once the whole face is worn. Store spare discs flat and dry in their box, and keep a box beside each set of timers so practicals are not held up by a worn disc.

What size is the Ticker Tape Carbon Disc?
The Ticker Tape Carbon Disc is 50 mm in diameter with a 4 mm hole. Check that your ticker tape timers take discs of this size before ordering, and ask us if you are unsure which disc your timers use.
How many discs are in a box of Ticker Tape Carbon Discs?
Ticker Tape Carbon Discs are packed in a box of 100. One box can keep several timers supplied across a series of motion practicals, and multiple boxes can be quoted for larger departments.
Which timers use the Ticker Tape Carbon Disc?
The Ticker Tape Carbon Disc is made for ticker tape timers, where a striker presses the disc against the paper tape to print dots. It suits timers that accept a 50 mm disc with a 4 mm hole; ask us to confirm the fit for your timer model.
When should a Ticker Tape Carbon Disc be replaced?
Replace a Ticker Tape Carbon Disc when the dots on the tape become faint or uneven even after turning the disc to a fresh area. Clear dots matter because students measure the spacing between them to work out speed and acceleration.
Does the Ticker Tape Carbon Disc include paper tape?
This listing covers the Ticker Tape Carbon Disc only, packed in a box of 100. Paper tape is not part of this item, so ask us through the contact page if you need tape or timers quoted with the discs.
