SWA-T Multi-Parameter Water Quality Online Monitoring System

Category Uncategorized

The SWA series water quality monitoring system is a multi-functional water quality monitoring system integrating control, sensing, wireless communication, and cloud platform.
It can monitor COD, TOC, turbidity, free chlorine/total chlorine (Constant voltage method, membrane covered method, DPD method), pH, conductivity, and water temperature in real time with optional parameters.
Water quality information is transmitted through the system to achieve on-site collection and detection. It can be transmitted in real time to the edge of the computing system, after the big data statistics, analysis, and automatic data verification, and cloud platform interaction.
