CTD-Diver

NEW

The new CTD-Diver comes with an upgraded memory size of 144,000 records, backup memory and is also available in a 200-meter pressure range.

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.

The CTD-Diver 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.

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 from 0 to 120 mS/cm.

The CTD-Diver can store 144,000 measurements with backup (date/time, pressure, temperature and conductivity).

The CTD-Diver has the following sample methods: fixed length intervals, event dependent, averaging and pumping test.

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