Worldwide Online Cod Analyzer Wastewater From China for Irrigation
Product Overview
- Product overview
Product Features
- The BOQU NHNG-3010 is an online, automatic ammonia-nitrogen (NH3–N) analyzer designed for continuous wastewater monitoring. It uses flow‑injection analysis: a peristaltic pump and NaOH carrier extract ammonia gas via a patented gas–liquid separator into a receiving solution (BTB indicator), and a colorimeter measures the photovoltage change to calculate NH3–N concentration. Typical factory ranges offered include 0–300 mg/L (customizable) and an automatic enrichment mode extends effective range up to ~1500 mg/L. Outputs include 4–20 mA, RS232/RS485 and a touch‑screen interface.

Product Advantages
- Flow injection analysis with patented gas–liquid separator (no complex pretreatment)
Application Scenarios
- Automatic enrichment for very wide measuring range (approx. 0.05 mg/L to 1500 mg/L)
- Non‑toxic, easy‑to‑prepare reagents (diluted NaOH + indicator)
- Automatic calibration, automatic residual reactant discharge and automatic resume after power/alarms
- Adjustable measurement/digestion and sampling intervals, monthly routine maintenance (~30 min)
- Data logging on alarms and power loss; outputs for remote monitoring and control
- Product value
- Enables reliable, continuous online monitoring of ammonia nitrogen to ensure regulatory compliance and process control
- Reduces manual sampling and labor costs while improving timeliness of corrective actions
- Lowers operational complexity and reagent hazards through simple, non‑toxic chemistry and minimal pretreatment
- Provides traceable data and alarm outputs to support decision making, reporting and irrigation water quality assurance
- Product advantages
- Independent intellectual property and engineered design from BOQU with world‑class instrument quality
- Simplified, low‑maintenance operation thanks to the patented gas–liquid separator and automated routines
- Broad dynamic range and good precision/stability (repeatability ≤±3%, stability ≤±10% over 24 h; accuracy specs per range)
- Flexible communication and control (4–20 mA, RS232/RS485, touch screen) and customizable measurement parameters
- Backed by BOQU’s manufacturing capability, customer service and supply‑chain integration
- Application scenarios
- Continuous monitoring of influent, process streams and effluent in municipal and industrial wastewater treatment plants
- Industrial process control and effluent compliance (chemical, pharmaceutical, food & beverage, textile, etc.)
- Quality control for reclaimed wastewater used in irrigation and agricultural reuse programs
- Aquaculture water quality monitoring and environmental monitoring projects or research labs requiring online NH3–N data
