This video demonstrates the setup, operation, and key moments of a multi-parameter water quality sensor for precise monitoring. Watch how the customizable electrode platform is assembled for different measurement needs, see the IP68 sensor deployed in a groundwater wellhead scenario, and learn how real-time data—pH, conductivity, dissolved oxygen, turbidity, and more—is transmitted via RS485 Modbus to the DATAIO cloud platform for visualization and analysis. Ideal for B2B viewers seeking practical insights into online water quality monitoring.
