Digital Sensors for Measuring Water Quality

With more than 50 years of experience in the development and the manufacturing of physicochemical sensors applied to the control of water quality, Ponsel (France) announces the DIGISENS range! Four digital sensors are offered: pH/redox/T°C ; Conductivity /Salinity/TDS ; Turbidity and Dissolved Oxygen operating on a principle of digital Modbus communication (RS485 and SDI12).

Séverine Vary, Ponsel’s product manager, explains: “We developed those sensors for field applications in order to integrate them to our portative device, the Odeon. Moreover, the protocols Modbus RS485/SDI12 enable compatibilities with dataloggers/transmisors as well as terminals equipped with suitable digital outputs (RS485 or SDI12). All calibration and traceability data are registered in the sensor which makes it clever and not dependent over a fixed exploitation system. Sensors are not only used for occasional measurement, but also for semi fixed and fixed condition in warning station (controls of upstream and downstream releases in WWTP), in the industry (regulation neutralisation), in aquaculture (monitoring of farms oxygenation) or even in integration on instrumented buoys.”
