Water Quality - Sensors
Robust, pluggable multi-parameter sensor made of plastic (PVC-U) for mounting up to twelve sensors (water level, temperature, conductivity, pH, redox potential, oxygen, turbidity, ammonia, nitrate, chloride, ammonium, sodium, calcium, fluoride, potassium, chlorophyll or cyano-bacteria-rhodamine WT)
Additional electric contact gauge function combined with KLL-Q-2 mobile field laboratory
Optimised design (Ø 89 mm, 572 mm length), usable starting from a 4"-diameter pipe
Output: RS485 (SHWP), Option: MODBUS, SDI-12, 0/4-20 mA
Optional: integrated, high-performance SEBA data logger Qualilog16 (for stationary use)
Individually configurable:
Depending on the measurement task at hand, the MPS-K16 can be individually equipped with a maximum of twelve water quality sensors and can detect up to 17 measurement parameters.
Simple handling:
Special bayonet locks grant the users a simple and quick replacement of worn sensors. The calibration and configuration of the MPS-K16 is done by means of a special USB-RS485 interface cable in connection with SEBAConfig operation software (Windows). This will automatically detect if a probe is spent and must be replaced.
Robust:
The housing of the MPS-K16 is made of durable plastic (PVC-U). The probe can thus be used even under adverse ambient conditions (e.g. landfill sites, contaminated sites).
Variable:
The proven and robust SEBA-connect feature of the MPS-K16 allows both the connection to mobile handsets (SEBA electric contact meter, KLL-Q-2, Checker-2) and stationary data collectors with (UniLogCom, LogCom/FlashCom) or without data transmission (Qualilog16).
