Description

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
