Conductivity Pod

Conductivity Pod

The Conductivity Pod is designed to work with PowerLab units (with Pod support), and conductivity electrodes for the monitoring of solution electrical conductance or resistance. The Conductivity Pod connects to any PowerLab hardware units with Pod ports (8- pin DIN inputs). PowerLab and MacLab (except 4s, 8s and 16s) units without Pod ports require the FE305 Pod Expander.

System Compatibility:

The Conductivity Pod is supported by the following versions of LabChart and Scope software:

WINDOWS

• LabChart v3.4.8 or later

• Scope v3.6.3 or later

MACINTOSH

• LabChart v3.6.3 or later

• Scope v3.6.3 or later

Note: Earlier software versions do not support Pods.

Transducer Compatibility:

The Conductivity Pod is recommended for operation with the MLT908, MLT915 or MLT916 electrodes. However, it can be used with most other types of two-electrode conductivity cells.

The following electrodes are suitable for use with the ML307 Conductivity Pod:

• MLT915 Dip-In Conductivity Electrode

• MLT908 Flow-Thru Conductivity Electrode (0.093ml)

• MLT916 Flow-Thru Conductivity Electrode (0.017ml)

Theory of Operation:

The Conductivity Pod measures the alternating current (AC) across a suitable conductivity cell by applying a AC potential across a pair of platinum plate electrodes that comprise the cell and outputs an analog voltage DC signal proportional to the conductivity (reciprocal resistance). The Pod has four gain settings with secondary amplification provided by the PowerLab range setting (see Specification section) to give a total of twelve input ranges.

The Pod incorporates a 20 Hz low pass filter to remove any high frequency interference. Further filtering options (down to 2 Hz) can be applied to the incoming signal with the PowerLab.
