Wide measurement range, high resolution:
The MPS-PTEC comes equipped with anautomatic meaasuring range switch (0-0.2 mS/cm; 0.2-2 mS/cm; 2-20 mS/cm; 20-200 mS/cm) which ensures that the best resolution is always available even with significant measuring range fluctuations.

Plug-and-play:
Convenient connection with a SEBA data logger via RS485 or process control systems (MODBUS, 0/4-20 mA), easy configuration and calibration via RS232-USB interface cable using operating software ConfigPC (Windows).

Last but not least:
In addition to conductivity measurement;  salinity, TDS values and water density can also be calculated and displayed.

Application:

  • Monitoring of conductivity, water level and water temperature in surface water: rivers, canals, springs, lakes
  • Groundwater: extraction wells, field measurement sites, landfill and construction sites
  • Other applications include: discharge monitoring, swelling pressure measurement
