Two Electrode Conductivity and Resistivity
The two electrode contacting conductivity sensor head series has a number of physical features that should be noted. The connector
is keyed. The key provides protection for the pins during installation. To insure that pins remain free of moisture and dirt, a rubber
boot is supplied with replacement sensor heads and should be kept in place when the sensor is being transferred or placed in storage.
In very humid or dirty environments, we also recommend applying some electrical grease to the connector pins.
Keep the O-Ring and the shaft of the sensor free of dirt. Be sure the DataStick cavity is also free of dirt and moisture prior to insertion.

Contacting Conductivity/Resistivity Overview
When a contacting conductivity sensor head is installed in the DataStick, AquaComm™ will automatically display conductivity or resistively,
temperature, sensor type and DataStick serial number. Pull-down menus will also automatically provide calibration, configuration and
diagnostic choices for conductivity.
