Optimized for multilevel measurements of temperature and conductivity in groundwater and surface water. In addition to the conductivity measurement, the parameters salinity, total dissolved solids (TDS) and water density can be calculated for each MPS-TEC segment.


Individually configurable:
The MPS-TEC conductivity chain can be adjusted to the individual measuring task. Two up to seven MPS-TEC segments can be configured to the required measuring depths with appropriate cable lengths.


High quality 4-electrode conductivity measuring cell. The MPS-TEC segments of the conductivity chain have a automatic subdivision of measuring ranger (0-0.2 mS/cm; 0.2-2 mS/cm; 2-20 mS/cm; 20-200 mS/cm), which ensures that the best possible resolution is always available, even with large fluctuations in the measuring range.


Robust and reliable:
Stainless steel housing made of 1.4539 can be used in extreme environmental conditions (landfills, contaminated sites, brackish water, etc.)


User-friendly and modular:
With SEBAConfigApp (Android, iOS) and the SEBA BlueCon you can communicate comfortably via Bluetooth with a smartphone or tablet with the logger. Using the plug-in module SlimCom for remote data transmission, the measurement chain can be upgraded to an online station. Easy connection to all SEBA data collectors (RS485) or process control systems (MODBUS, 0 / 4-20 mA).

  • Redundant long-term monitoring of temperature and conductivity in groundwater and surface water
  • Spatio-temporal high-resolution observation of the saltwater intrusion dynamics, e.g. in coastal aquifer systems
  • Precise salinity monitoring of saline groundwater
