We are seeking an online water quality monitoring system for continuous installation to assess incoming water at our facility. The system should support signal transmission via 4–20 mA or RS-485 and measure key parameters including conductivity, turbidity, total hardness, pH, and temperature. Please provide a detailed quotation that includes the technical datasheet, warranty information, delivery lead time, and available user manuals. Additionally, your recommendations for the most suitable models for industrial applications focused on raw water monitoring would be greatly appreciated.
