Diver Steel Cable

Copper Shield

Protect CTD-Divers from Bio-Fouling


The Diver Copper Shield protects the CTD-Diver from bio-fouling and reduces maintenance cost. There are many methods that can be used to prevent and remove the bioaccumulations. However, these methods can be expensive and detrimental to the environment. There is a lesser known natural solution that is a good match for the CTD-Diver and is effective at reducing the development of microorganisms. The Diver Copper Shield is a copper coil shield specifically designed to significantly reduce the growth of algae on the electrodes. Thus reducing the need for maintenance and reducing the time spent on site.

What is bio-fouling?

Bio-fouling is the undesirable accumulation of microorganisms, plants, algae, or animals on wetted structures. This is especially prominent in surface water monitoring in warm environments. Bio-fouling causes an algal growth on the electrodes of the CTD-Diver. This may affect the conductivity readings and increases the need for maintenance. Removing the biological materials from the electrodes can be damaging over a prolonged period of time and increase time spent in the field.

  • Lower maintenance intervals
  • Reduced algae growth on the conductivity sensor
  • Improved conductivity readings
  • Easy to install and use
