Online Nitrogen Analyzer Product Wholesale - BOQU

Product Overview

- The AME-2000 is an online residual chlorine analyzer with a compact, robust design developed by Shanghai Boqu Instrument Co., Ltd. It uses the national-standard DPD colorimetric method with automatic reagent dosing for continuous, real-time measurement of free/chlorine residuals. The unit includes a touchscreen display and supports data storage and export.

Product Features

- Measuring principle: DPD colorimetry with automatic reagent addition.

- Measuring range: 0–5.00 / 10.00 mg/L; resolution 0.01 mg/L.

- Precision: larger of ±5% of reading or ±0.03 mg/L.

- Fast analysis: typical analysis cycle ~2.5 minutes; measurement interval configurable from 120 s to 86,400 s.

- Outputs & interfaces: 4–20 mA analog (max 500 Ω), RS485 (Modbus RTU), two relay alarm outputs.

- Operation & UI: 4.3" color LCD touchscreen, selectable auto/manual modes, data storage with U?disk export, bilingual (Chinese/English).

- Power & physical: 100–240 VAC, 50/60 Hz; recommended sample flow ~1 L/min; compact dimensions and ~6.5 kg weight.

Product Value

- Provides reliable, continuous monitoring of residual chlorine to ensure disinfection efficacy and regulatory compliance.

- Automation (automatic dosing, calibration, data logging and remote communication) reduces manual sampling, labor and human error.

- Fast, frequent measurements enable timely control actions to maintain safe chlorine levels in treatment and distribution systems.

- Data export and communication simplify integration into plant control systems and record-keeping for audits.

Product Advantages

- Uses national-standard DPD colorimetry for accurate and stable measurements.

- Wide power input and robust build for flexible installation.

- Comprehensive outputs (4–20 mA, RS485 Modbus) and alarm relays for PLC/SCADA integration and remote supervision.

- Touchscreen interface and onboard data storage/U?disk export for easy operation and historical analysis.

- Backed by BOQU’s quality assurance, experienced R&D team, and established sales/service network.

Application Scenarios

- Online monitoring of residual chlorine during chlorination and disinfection in water treatment plants.

- Continuous surveillance of chlorine levels in drinking water distribution networks and pipe systems.

- Any facility requiring automated residual chlorine measurement for safety and compliance (municipal water utilities, industrial water systems, disinfection processes).
