Use the Drop Counter to perform accurate titrations. This accessory greatly improves the process of using a dropper without vision.
Record the number of drops or calibrate the drop size to record volume of titrant added during a titration. It may be used in conjunction with other sensors, such as a pH Sensor, Conductivity Probe, or ORP Sensor to perform conductimetric or potentiometric titrations.
