VanEssen CTD-Diver Differential Pressure Recorders or each millimeterWhere 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 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
