iSPA-T Multi-parameter Water Quality Online Monitoring System

The iSPA series water quality monitoring system is a multi-functional water quality monitoring system integrating control, sensing, wireless communication, and cloud platforms. The iSPA series water quality monitoring system 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 can be collected and detected on-site through this system, transmitted to the monitoring system in real-time, and interacted with the cloud platform through significant data statistics, analysis, and automatic data verification. It can realize closed-loop control of the pump room, laying a solid foundation for constructing an unattended smart water supply platform.

Quick measurements with a minimum cycle time of 10 seconds
Self-cleaning module for long-term maintenance-free operation
Multi-parameter integration can measure turbidity, free chlorine / total chlorine, pH, COD, TOC, conductivity, water temperature
The system supports 4G wireless transmission, through which users can transfer data to the cloud platform
Users can set the threshold value of water quality parameters; the water quality that exceeds the set threshold value will trigger the system alarm.
