Drop Counter

Drop Counter

Drop Counter

Use the Drop Counter to perform accurate, automatic titrations. Record the number of drops or calibrate the drop size to record volume of titrant added during a titration.

Education Levels

The Drop Counter precisely records the number of drops of titrant added during a titration, which is automatically converted into volume. It may be used in conjunction with other sensors, such as a pH Sensor, Conductivity Probe, or ORP Sensor to perform conductometric or potentiometric titrations.

The Vernier Drop Counter has many features that help simplify its use:

  • Adjustable clamp, fits most laboratory ring stands and lattices
  • Wide drop-detecting area
  • Large sensor slot, fits most conventional stick-style sensors
  • Smaller, adjustable slot for temperature sensors
  • Accurate drop counting at rates up to 6 drops/second
