Expert in Water Quality Measurement and Water Treatment Project Since 2007
Product Overview
1) Product overview
Product Features
- BOQU’s new online wastewater analyzer (presented in the supplied introduction as the NHNK-1000 Online Ammonia Nitrogen Analyzer) is a compact, certified instrument designed for continuous in-situ measurement and control of ammonia nitrogen (NH4‑N) in wastewater. It provides real‑time data and factory-backed production and service from Shanghai Boqu Instrument Co., Ltd. Calibration is performed against a lab photometric reference to automatically account for matrix effects.

Product Advantages
- Measuring range: NH4‑N 0.1–1000 mg/L (K+ optional 0.5–1000 mg/L); pH range 5–10. Accuracy: NH4‑N ±5% or ±0.2 mg/L (greater); temperature ±0.1°C; pH ±0.1.
Application Scenarios
- Outputs/communication: RS485 Modbus RTU (native), optional 4–20 mA. Power: AC220V or DC24V. Resolution NH4‑N 0.01 mg/L.
- Mechanical/electrical: transmitter IP65, sensor IP68, standard 10 m cable (extendable to 100 m). Sensor uses an NH4+ ion‑selective electrode (grid film with organic ion‑exchange membrane). Real‑time data transmission and integrated online help.
3) Product value
- Enables continuous, automated ammonia monitoring and process control to improve discharge compliance and optimize aeration/control strategies. Reduces need for frequent lab standard calibrations (matrix effects handled by initial photometric reference), lowers operational costs (claimed up to 50% savings), and supports faster, data‑driven decision making in treatment operations.
4) Product advantages
- High precision, long‑term stability and strong anti‑interference performance due to ion‑selective electrode design. Low initial investment and reduced OPEX versus traditional approaches. Robust protection ratings for field use (IP65/IP68), flexible communication/output options, and simplified calibration workflow that removes routine standard calibrations.
5) Application scenarios
- Primary: municipal and industrial wastewater treatment plants for aerobic control and discharge monitoring of ammonia nitrogen. Also suitable for drinking water monitoring, fertilizer and refrigerant process streams, industrial process water and other water quality monitoring applications where continuous NH4‑N measurement and control are required.
