4.1 Conductivity (C)

RBR CT | uv and CTD | uv instruments use integrated inductive conductivity sensors which measure the ability of
seawater to conduct electric current.

* For a clean cell with no biofouling.
The CT cell is rugged and durable. It is not affected by surface contaminants or freezing conditions, and can be frozen
into ice.
While 80% of its volumetric measurements happens inside the cell, they also extend up to 15cm away and thus may be
affected by conductive and non-conductive objects within this distance. RBR calibrates conductivity sensors to account
for static objects, such as cages, guards, and other sensors.

To maintain optimal accuracy, deploy your instrument at least 15cm away from other objects.
Conductivity measurements are temperature compensated.
