Vernier Drop Counter

Vernier's new Drop
Counter is an optical sensor that
accurately records the number of
drops of titrant added during a
titration. The Drop Counter software
can automatically convert the number
of drops into volume. It will also
record pH and temperature values and
calculate the first and second
derivatives of the pH for easy
equivalence point determination. The
Drop Counter can also be used for
conductimetric or potentiometric
titrations using our Conductivity
Probe, Ion-Selective Electrodes or
any electrode with a 0 to 5-volt
output. You could even use it
instead of a utility clamp anytime
you need to hold an electrode in
place.
The Vernier Drop
Counter can be used with your own
buret or with the Reagent Reservoir
included. This reservoir was
designed to keep the drop size
consistent and to make drop rate
regulation simple and easy. In
addition, we include a Vernier
Microstirrer-a magnetic stirring
paddle that slips onto the tip of
your pH Sensor. When used with any
magnetic stirring plate, the
Microstirrer provides a faster
response after each drop added.
