Reliable Cod Sensor for Hospital

Product Overview

Note: the text you provided describes BOQU’s NNA-210-1 digital nitrate (NO3–N) sensor, not a COD sensor. Below I’ve summarized the supplied product information in the five requested areas. If you actually want a summary written specifically for a “Reliable COD Sensor for Hospital,” tell me and I will adapt this content accordingly.

Product Features

1) Product overview

Product Value

- BOQU NNA-210-1 is a digital online nitrate-nitrogen (NO3–N) sensor that uses UV absorption at 210 nm to measure nitrate concentration in flowing water.

Product Advantages

- Key specs: measuring range 0.1–100.0 mg/L NO3–N, accuracy ±5%, resolution 0.01 mg/L, working temp 0–45 °C, IP68 protection, RS485 (Modbus RTU) communication, DC12V power, 10 m standard cable (extendable).

Application Scenarios

2) Product features

- Direct, continuous online measurement without sampling or chemical reagents.

- UV-absorption spectrometry (210 nm) for nitrate detection.

- Automatic cleaning function to reduce maintenance and fouling.

- Fast response, high repeatability (±2%), and digital RS485 output for integration.

- Robust construction options (SUS316L body for freshwater, titanium alloy for seawater) and protections (reverse polarity, power terminal protections).

3) Product value

- Provides reliable real-time data for nitrate levels to support process control, regulatory compliance, and early warning of contamination.

- Eliminates reagent costs and secondary pollution associated with lab-based tests.

- Reduces manual sampling and maintenance workload via continuous monitoring and automatic cleaning.

- Enables integration into SCADA/PLC systems through Modbus RTU for automated responses and data logging.

4) Product advantages

- Certified materials and industry-standard manufacturing quality.

- Wide measurement range and fine resolution suitable for both low-level and high-level monitoring.

- Durable, corrosion-resistant construction (titanium option) and IP68 protection for long-term deployment.

- Built-in protections (power reverse-connection, protected RS485 terminals) increase reliability in field installations.

- Low-maintenance operation (no reagents, automatic cleaning) lowers lifecycle costs.

5) Application scenarios

- Drinking water and surface water quality monitoring.

- Industrial process water and production water monitoring.

- Sewage and wastewater treatment plants — continuous monitoring of nitrate in aeration tanks and for denitrification control.

- Any remote or online monitoring system requiring Modbus integration and reliable field deployment (including environmental monitoring networks).

- (If needed in hospital contexts) can be applied to monitoring hospital wastewater streams or facility process water where nitrate monitoring is required.

If you want the same five-point summary tailored specifically to a COD sensor for hospital use, I can rewrite this focusing on COD measurement method, hospital wastewater standards, and relevant hospital application scenarios.
