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