Cells that have been contaminated with foreign material generally read low of the actual conductivity. Your zero (in air) conductivity reading is generally unaffected. The conductivity error due to fouling will generally be proportional to the conductivity value....

What is the effect of temperature drift on practical salinity for my CTD?
Example Data: Temperature and Conductivity are two of the most important values taken into consideration when our instrument calculates the practical salinity of seawater. When one sees a change in a measured value, such as temperature, that change will affect your...
How can I tell if the conductivity cell on my CTD is broken?
Conductivity cells are made of glass, which is breakable. If a cell is cracked, it typically causes a salinity shift or erratic data. However, if the crack occurs at the end of the cell, the sensor will continue to function normally until water penetrates the epoxy...
