Conductivity
Probe
(Order Code CON-BTA)
The Conductivity Probe can be used to
measure either solution conductivity or
total ion concentration of aqueous samples
being investigated in the field or in the
laboratory. Conductivity is one of the most common environmental tests of aquatic
samples. Even though it does not tell you specific ions that are present, it quickly
determines the total concentration of ions in a sample.

What's Included
Conductivity Probe
90 mL bottle of 1000 µS/cm NaCl standard solution
Compatible Software and Interfaces
See
www.vernier.com/manuals/con-bta
for a list of interfaces and software
compatible with the Conductivity Probe.
Getting Started
1. Connect the sensor to the interface (LabQuest Mini, LabQuest 2, etc.).
2. Start the appropriate data-collection software (Logger
Pro
, Logger Lite,
LabQuest App) if not already running, and choose New from File menu.
The software will identify the sensor and load a default data-collection setup. You
are now ready to collect data.
If you are collecting data using a Chromebook™, mobile device such as iPad
®
or
Android™ tablet, or a Vernier wireless sensor or interface, please see the following
link for up-to-date connection information:

Using the Product
1. Set the range switch on the sensor.
2. Thoroughly rinse the lower section of the probe using distilled or deionized
water.
3. Connect the sensor following the steps in the Getting Started section of this
user manual.
4. When you are finished making measurements, rinse the electrode with distilled
water. Store dry.

Calibration
For many experiments, calibrating the Conductivity Probe is not required. A
calibration equation is stored on each probe before they are shipped, which is used
as a default by Vernier software.
For the most accurate measurements with this sensor, we recommend calibration. It
is a simple process that takes only a few minutes.
For instructions for Conductivity Probe calibration using Logger
Pro
computer
software, see

In order to calibrate a Conductivity Probe, or to confirm that a saved calibration is
accurate, you should have a supply of conductivity standard solutions that cover
the range of the conductivity values you will be measuring. For more information
about conductivity standard solutions, including recipes for preparation, see
