Accurately records the number of drops of titrant added during a titration. The Drop Counter also conveiently holds the electrode of a pH meter, conductivity meter, or ion-selective electrode in place. Includes dispensing vessel for uniform drop size, connecting cable, and software. The software converts the number of drops into volume, and will also record the pH and temperature values and calculate the first and second derivatives for easy equivalence point determination. For CBL 2 only.
