Accurate Automated Titrations

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.

Use one of the 7 pre-calibrated ranges or count the drops and calibrate to the drop size. Accuracy is to the volume of the last counted drop.
