3 Parameters in 1 Housing
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 rugged, corrosion proof ceramic housing, is the instrument of choice.

The CTD-Diver is equipped with a four-electrode conductivity sensor that measures electrical conductivity from 0 to 120 mS/cm. There are two options for measuring conductivity: true or specific conductivity at 25 °C. Additionally, pressure and temperature are measured and recorded.


  • Innovative ceramic housing technology
  • Three sensors in one sealed housing
  • Conductivity range up to 120 mS/cm
  • Compact size: Ø 22 mm - length 135 mm
  • Various measurement methods
  • 48,000 records of time stamp, pressure, temperature, and conductivity
  • 30-point pressure factory calibration


  • Corrosion proof
  • Monitor conductivity, water levels, and temperature
  • Suitable for use at most sites
  • Easy installation in almost every well
  • Event based, averaging, and pumping tests sample methods to conserve memory
  • Cost-effective frequent, long-term measuring
  • Reliable and accurate data


  • Monitoring saltwater intrusion
  • Water quality monitoring for agriculture; remediation; to correlate conductivity with salt, TDS, permanganate, nitrate, sulfate
  • Tidal fluctuations monitoring
  • Estuary and wetlands monitoring
  • Leachate monitoring at landfill sites
  • Aquifer storage and recovery
  • Monitoring network automation
  • Groundwater monitoring projects
  • Mining (tailings, environmental, slope stability)
