The pole-mounted water quality monitoring system adopts real-time, online, full-spectrum automatic monitoring technology and multi-parameter integration technology. It can be equipped with various sensors to realize real-time online monitoring of water quality, weather, rainfall, flow, etc. The monitoring data is transmitted to the server receiving terminal through wireless network (GPRS/CDMA/BeiDou). Real-time data can be viewed through system management software and application service platform, thereby realizing long-term monitoring and comprehensive evaluation of water quality in nearshore areas, river sections or reservoirs, and providing timely and effective data and technical support for water environment protection, scientific research, and public services.
• No reagents required, easy to install and maintain;
• Short measurement time;
• Can be powered by mains or solar energy, low power consumption, low operating cost;
• Wireless network (GPRS/CDMA/BeiDou) transmission.
