The drop & bubble counter is perfect for highly accurate automated titrations. It can be used to count either drops of fluid falling from a dropping device e.g. during a titration, or bubbles rising through fluid in a column. The counter makes use of an infrared beam which when interrupted (e.g. by a drop or bubble) creates a digital signal that is counted. A red LED indicator will blink as a drop or bubble passes. There is a small button close to the indicator that can be pressed to reset a count to zero.
