Used with conductivity cells for monitoring solution conductance. The Pod measures the alternating current across a suitable conductivity cell by applying an AC potential across the pair of platinum plate electrodes that comprise the cell. The output is proportional to the conductivity of the solution. The signal is scaled to read in µS or mS, depending on the range, 5 µS to 20 mS, selected.
For use with:
The Pod can also be used with most other conductivity electrodes with a BNC connector.
- Four gain settings with secondary amplification provided by the PowerLab range settings to give a total of twelve input ranges.
- A 20 Hz low pass filter to remove any high frequency interference.
- Further filtering options (down to 2 Hz) using the PowerLab.
