Where there is a need to monitor groundwater levels and salt water
intrusion , injected wastewater, or contamination from chemical discharges and
landfill sites, the CTD-Diver® with its 22 mm diameter rugged, corrosion proof
ceramic (zirconium-oxide) housing, is the instrument of choice.
The CTD-Diver is a submersible
datalogger for long-term uninterrupted, real-time water level monitoring using
a pressure sensor when submerged at a fixed level under the water surface. The
pressure sensor measures the equivalent hydrostatic pressure of the water above
the sensor diaphragm to calculate the total water depth. In addition, to a
pressure sensor the CTD-Diver is also equipped with a 4-electrode conductivity
sensor for measuring the true or specific electrical conductivity of the water.
The Diver autonomously measures conductivity, pressure and temperature and
records them in its internal memory. The Diver is ideal for ground and surface
water level applications.
