The CTD Diver, with its rugged, corrosion-resistant 22 mm diameter ceramic (zirconia) housing, is the instrument of choice for monitoring groundwater levels and saltwater intrusion, discharged wastewater, or contamination from chemical discharges and landfills.
The CTD Diver is a submersible data logger for long-term, uninterrupted, real-time water level monitoring using a pressure sensor when submerged at a fixed level below the water surface. The pressure sensor measures the equivalent hydrostatic pressure of the water above the sensor membrane to calculate the total water depth. The ceramic housing is suitable for use in brackish or salt water and aggressive environments.
Connect the diver to a modem to transfer the collected data directly from the field to your data center.
The CTD Diver is the ideal choice for groundwater and surface water applications. The water logger is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. This type of measuring cell is relatively insensitive to sensor contamination, so maintenance is kept to a minimum.

A change in conductivity can be caused, for example, by changes in water flow or by increasing/decreasing pollution or salinization. The CTD-Diver measures the conductivity of a solution and can be programmed by the user to measure either true conductivity or specific conductivity at 25°C.
