The CTD-Diver is a robust instrument designed for monitoring water in some on of harshest settings. Its corrosion proof ceramic casing makes it ideal for measuring saltwater intrusion, injected wastewater as well as contaminated water often found at landfill sites.

The CTD Diver is equipped with a four-electrode connectivity sensor that measures electrical conductivity from 0 to 120mS/cm. You can choose to measure either true or specific conductivity at 25 °C. The CTD Diver can also be used to measure and record water pressure and temperature.
