Product Overview

Note: the provided product description actually details BOQU’s BH-485-NO3-N digital nitrate-nitrogen sensor. Below is a concise 5‑point summary based on that detailed introduction.

Product Features

1) Product overview

Product Value

- BOQU BH-485-NO3-N is an integrated digital online nitrate-nitrogen sensor (ISO9001 production) that uses ion-selective electrode technology with RS485 Modbus communication.

Product Advantages

- The sensor combines nitrate ISE, optional potassium ISE, pH and temperature electrodes in one probe for mutual compensation and multi-parameter measurement.

Application Scenarios

- Rugged IP68 construction, compact (55 mm × 340 mm), DC12V supply, standard 10 m cable (extendable to 100 m).

2) Product features

- Direct, continuous in-situ nitrate-nitrogen measurement without reagents or sample conditioning.

- Optional potassium (and chloride) compensation to reduce cross-sensitivity and improve accuracy.

- Integrated pH and temperature sensing for automatic correction; fast response time (≤2 minutes).

- Digital RS485 Modbus RTU output, reverse-polarity protected, low maintenance and high precision.

- Wide measuring range (NO3-N 0.1–1000 mg/L) and IP68 protection for basin/rack mounting.

3) Product value

- Low operating cost by eliminating reagents and sample pumps and reducing manual sampling/maintenance.

- Enables process optimization (e.g., aeration control and denitrification) and energy savings through real-time trend data.

- Improves reliability and data integrity for predictive maintenance and regulatory compliance with continuous monitoring.

- Multi-parameter compensation yields more trustworthy readings in complex matrices.

4) Product advantages

- Integrated multi-electrode design gives robust, compensated measurements versus standalone probes.

- Robust ion-selective membranes and industrial-grade enclosure for prolonged field life.

- Proven quality control (ISO9001) and user-friendly digital interface (RS485) for easy system integration.

- Good analytical performance: NO3‑N resolution 0.01 mg/L, accuracy ±5% or ±0.2 mg/L, response ≤2 min.

- Simple basin-rim installation—no measuring container or transfer pump required.

5) Application scenarios

- Online monitoring and control in municipal and industrial wastewater treatment plants (nitrification/denitrification, aeration optimization).

- Continuous effluent monitoring for regulatory compliance and process control.

- Remote or distributed monitoring where reagent-free, low-maintenance sensors are preferred.

- Environmental water quality trend measurement in basins or tanks, and process monitoring in relevant industrial plants.
