Multiparameter probe MPS-D8/Qualilog8

Robust, pluggable multi-parameter sensor from 1.4404 stainless steel to accommodate up to eight sensors (water level, temperature, conductivity, pH, redox potential, oxygen, turbidity, etc.)

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.

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).

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).
