Conductivity Probe, order code CON-BTA, $95
Specifications and User Guide

TROUBLESHOOTING
-Primary Test: Place the toggle switch at the desired setting, run the data-collection program, and take a reading in a solution of known TDS. Suggest using the calibration solution that comes with the probe. It is 500 mg/L TDS or 1000 microsiemens/cm.
-Secondary Test: If you change the setting of the toggle switch while Logger Pro, DataMate, or DataPro is running, reset the program so that the calibration equation for the new setting is selected.

CALIBRATION
-You do not have to perform a new calibration when using the Conductivity Probe for most experiments in the classroom. However, if your experimental application requires more accurate readings, you should calibrate your sensor.
-See the user manual for calibration instructions: Specifications and User Guide
