System & Equipment Online Water Analyzer Wholesalers

Product Overview

- QILEE Online Water Analyzer is an automated spectrophotometric instrument for continuous online measurement of ammonia nitrogen.

- Built to international standards for reliable field and laboratory use, it supports touch-screen control, alarm and data retention, and automatic recovery after power or fault events.

- Base measurement specification is 0–300 mg/L (selectable ranges); with the built-in automatic enrichment function the effective span extends from about 0.05 mg/L up to ~1500 mg/L.

Product Features

- Analytical method: salicylic-acid spectrophotometric detection with adjustable chromogenic time (5–120 min) and minimum measurement cycle of 30 minutes.

- Wide dynamic range via automatic enrichment; selectable measurement sub-ranges (0–10, 10–150, 10–300 mg/L).

- Low-dosage, non-toxic reagents (dilute NaOH and indicator in distilled water) for easy preparation and safe operation.

- Simplified instrument design with gas–liquid separator—no complex sample pretreatment or routine instrument cleaning required.

- Connectivity and control: 4–20 mA (2 channels), RS232/RS485, adjustable sampling/calibration intervals, and touch-screen interface.

Product Value

- Delivers accurate, continuous ammonia-nitrogen monitoring over very low to very high concentrations, supporting regulatory compliance and process control.

- Low operational and maintenance costs reduce total cost of ownership (simple reagents, minimal pretreatment, limited cleaning).

- Fast deployment and stable operation enable reliable on-site or online monitoring with preserved data during power/fault events.

- Flexible configuration and company technical support simplify integration and customization for different sites.

Product Advantages

- Ultra-wide measurable range (with enrichment) and good accuracy: ≤±10% for ≥0.2 mg/L and ≤±0.02 mg/L for

- User-friendly and safe: non-toxic reagents, distilled-water solvent option for concentrations >0.2 mg/L, and touch-screen operation.

- Reduced infrastructure needs: gas–liquid separator removes need for bulky pretreatment hardware and lowers system complexity.

- Robust data handling and automation: alarms, data retention on power loss, automatic purge and resume after reset/power recovery.

Application Scenarios

- Continuous online and rapid on-site or laboratory monitoring of ammonia nitrogen in rivers, lakes, and drinking/tap water.

- Industrial and municipal wastewater monitoring, including discharged effluent, high-concentration sewage and process streams.

- Industrial water reuse, factory upgrades, and high-purity process water quality control where broad-range ammonia monitoring is required.

- Modular/containerized or plug‑and‑play water treatment installations that need integrated, low-maintenance analytical instrumentation.
