Counter Pen is a combination marker and digital counter that can be used to count cell growth on petri dishes, inventory parts, and tally samples received. To ensure an accurate tally, the counter beeps each time a mark is made, and the easy-to-read LCD displays the total (up to 99,999). Pen features on/off switch and comes with cap.
