Drop Counter

$109.00

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.

ORDER CODE: VDC-BTD Categories ,
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
