Fisherbrand™ Counter-Pens can be used to count cell growth on Petri dishes, inventory parts, or tally samples received. Combination marker/digital counter suits both laboratory and plant use.

Each time a mark is made with the felt-tipped pen, the counter beeps and its easy-to-read LCD displays the count.


  • Marks hold your place while counter tracks your total
  • Touch, sound, and count occur simultaneously
  • Counter reads to 99,999
  • Fail-safe reset
