Online Water Analyzer Online Water Analyzer Manufacturer

Product Overview

- QILEE Online Water Analyzer is an automated, online total nitrogen analyzer designed for international markets.

- It uses alkaline potassium persulfate digestion combined with UV spectrophotometry to convert and measure all nitrogen species as nitrate nitrogen.

- The instrument is compact (800×430×300 mm), touch-screen operated, provides 4–20 mA and serial outputs (RS232/RS485), and resumes operation automatically after power or abnormal events.

Product Features

- Selector valve assembly: precise control of reagent sampling sequence for orderly analysis.

- Sampling assembly: peristaltic pump with negative-pressure suction and an air buffer to protect pump tubing and extend life.

- Metering assembly: photoelectric visual metering enables accurate micro-dosing (1.5 ml per dose) and compensates for pump tube wear.

- Sealed high‑temperature/high‑pressure digestion: complete oxidation of nitrogen compounds at ~120–124°C while preventing corrosion from volatile gases.

- Durable reagent tubing: imported PTFE transparent hoses (ID >1.5 mm) reduce blockages and simplify maintenance.

- Flexible operating parameters: dual-range measurement (0–20 mg/L and 0–100 mg/L), measurement cycle ≤50 min, adjustable sampling/calibration intervals, and monthly maintenance (~30 min).

Product Value

- Provides continuous, reliable online monitoring of total nitrogen to support regulatory compliance and process control.

- Low reagent consumption and precise micro-dosing minimize operating costs (reagent cost

- Automated recovery, alarms, data retention on power loss, and digital outputs enable easy integration into plant control and SCADA systems.

- Reduces downtime and maintenance effort through corrosion-resistant sealed digestion and clog-resistant PTFE tubing.

Product Advantages

- High analytical reliability from sealed digestion and accurate photoelectric metering, delivering stable repeatability (±3%) and good short-term stability (≤±10% in 24 h).

- Extended component life and lower maintenance frequency due to protected pump design and robust reagent tubing.

- Cost-effective operation with low reagent usage and simple monthly servicing.

- Export-proven product with established sales in multiple countries and professional after‑sales support from an experienced manufacturer.

Application Scenarios

- Online monitoring of total nitrogen in industrial wastewater streams (chemical, pharmaceutical, food processing, etc.).

- Continuous discharge monitoring and compliance checking for municipal sewage treatment plants.

- Process control and quality assurance in factory wastewater treatment, reuse systems, and high-purity water production lines.

- Any facility requiring automated, real-time nitrogen monitoring with digital integration to control systems or environmental reporting.
