Individually configurable:
Depending on the measuring task at hand, the MPS-D8 can be individually equipped with a maximum of eight water quality sensors and can detect up to 13 parameters.

Simple handling:
Special bayonet locks grant the users a simple and quick replacement of worn sensors. The calibration and configuration of the MPS-D8 is carried out using a special USB-RS485 interface cable together with ConfigPC operating software (Windows). This will automatically detect if a probe is spent and must be replaced.

Robust:
The housing of the MPS-D8 is made of high-quality 1.4404 stainless steel. The probe can thus be used even under adverse ambient conditions (e.g. landfill or other contaminated sites).

Variable:
The proven and robust SEBA plug system of the MPS-D8 allows both the connection to mobile handsets (SEBA KLL-Q-2 Type electric water level gauge (KLL), Checker-2) and stationary data collectors with data transmission (UniLogCom, LogCom/FlashCom) or without data transmission (Qualilog8).

  • Water quality monitoring
  • In surface waters: rivers, canals, springs, lakes
  • Groundwater: extraction wells, field measurement sites, landfill and construction sites
  • Other applications: discharge monitoring
