This spectrometer-based Sensor measures Nitrate Nitrogen (NO3-N) directly via its absorption of 210 nm UV light.

As water flows through the sensor slit, a portion of the light is absorbed by the sample, while the remaining light passes through, reaching the opposite side of the sensor. This absorption is used to calculate nitrate concentration.

Main Features

• Direct Measurement: Measures nitrate nitrogen directly from the sample without the need for pre-processing or sampling.
• Eco-Friendly Operation: Requires no chemical reagents, eliminating secondary pollution.
• Fast, Continuous Monitoring: Provides a rapid response time with real-time, continuous online measurement.
• Low Maintenance: Features an automatic cleaning function to reduce maintenance demands.
• Built-In Protection: Includes positive and negative reverse connection protection for reliable power supply use.
• RS485 Terminal Safety: Power supply protection for RS485 A/B terminals for secure connectivity.

Applications

• Drinking and Surface Water: Ideal for nitrate monitoring in drinking water sources and natural water bodies.
• Industrial Water and Wastewater: Suitable for industrial process water and wastewater treatment applications.
• Nitrate Monitoring: Designed for continuous monitoring of nitrate concentration in water, especially beneficial for managing sewage aeration tanks and denitrification processes.
