This is an industrial grade online nitrate ion sensor that uses PVC membrane ion selective electrode method to detect nitrate concentration in water in real time. The default range is 0~100 mg/L (optional 0~1000 mg/L), with an accuracy of ± 5% or ± 2 mg/L, and a response time of less than 60 seconds. Built in Pt1000 automatic temperature compensation, supports RS-485 (Modbus RTU) output and optional 4-20mA, making it easy to connect to PLC, DCS and other systems. 3/4 NPT thread installation, IP68 protection, optional POM+316L corrosion-resistant material for housing, suitable for sewage treatment, surface water monitoring, pipeline and tank immersion measurement.

This solar-powered nitrate ion sensor operates on self-sustaining photovoltaic power, requiring no external power supply or wiring, and is suitable for various outdoor water environment monitoring scenarios. It features high detection accuracy and fast response speed, enabling real-time and precise collection of nitrate ion concentration data in water. With stable operation and low power consumption, it is widely used in aquaculture, rivers, lakes, municipal sewage, field water environments and other fields. Its integrated design allows for easy installation and supports long-term uninterrupted online monitoring, facilitating water quality control and environmental monitoring.
