CTD-Diver

The CTD-Diver is ideal for ground and surface water applications.

Where there is a need to monitor groundwater levels and saltwater 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. It autonomously measures conductivity, pressure, and temperature and records them in its internal memory. The CTD-Diver is ideal for ground and surface water level applications.

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. The 4-electrode conductivity sensor measures the true or specific electrical conductivity of the water from 0 to 120 mS/cm.

The CTD-Diver can store a maximum of 144,000 measurements (date/time, pressure, temperature, and conductivity) in its working memory and 144,000 measurements in its backup memory.

The CTD-Diver has the following sample methods: fixed length intervals, event-dependent, averaging, and pumping tests. The measurements are stored in fixed length or continuous memory (fixed length only).

The CTD-Diver is available in the following pressure ranges 10 m, 50 m, 100 m, and 200 m.
