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.
Description
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
