Product description

The Rika Sensor RK500-09 Water Quality Sensor redefines efficiency in remote environmental monitoring of water resources. This device allows customizing the sensor configuration according to project needs, choosing between Dissolved Oxygen (DO), COD, pH, ORP, EC/Salinity, NH4+, and Turbidity. Its digital architecture allows all this data to be consolidated into a single Modbus output, simplifying the infrastructure of any environmental IoT station.

What sets the RK500-09 apart is its adaptability: the interval and cycles of its self-cleaning brush can be programmed to adjust to the turbidity or specific dirtiness of the monitored water. This feature, combined with its high-protection coating, makes it ideal for prolonged deployments in treatment plants, rivers, or aquaculture systems. As an environmental field sensor, it ensures that accuracy is not compromised by biofouling, guaranteeing reliable data for real-time decision-making.
