Drop Counter

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

• Acid-Base Titration (Computer)

  Use a Vernier pH Sensor, Stir Station, Drop Counter and computer to perform an acid-base titration.
