CTD-Diver
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 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.
