Online COD BOD Analyzer Algae Online Analyzer Factory Direct Supply
Product Overview
- The product is an online water-quality analyzer from BOQU Instrument (model TNG-3020) designed for automatic, continuous monitoring of total nitrogen (TN) in water.
- It uses resorcinol spectrophotometry and requires no sample pretreatment: the probe/sample riser can be inserted directly into the measured stream.
- Measurement capability covers three ranges (0–10, 0.5–100, 5–500 mg/L TN) with high sensitivity (±0.05 mg/L for values ≤0.5 mg/L) and repeatability ≤±5%.
- Built for industrial and environmental monitoring with touch-screen operation, data retention on alarms/power loss, and standard outputs (4–20 mA, RS232/RS485).
Product Features
- Eco-friendly construction and factory-level quality control to ensure reliable performance.
- Precise reagent dosing via a visible photoelectric metering system (trace doses ≈1.5 ml), reducing quantitative errors from peristaltic pump wear.
- Select valve assembly for controlled reagent/sample timing and a negative-pressure peristaltic injection design that protects pump tubing.
- Sealed high-temperature, high-pressure digestion module for faster, safer reactions and reduced gas volatilization/corrosion.
- Durable PTFE transparent reagent tubing (≥1.5 mm ID) to minimize clogging; configurable digestion time (5–120 min) and sampling/calibration intervals.
Product Value
- Enables real-time, unattended monitoring for regulatory compliance and process control — reducing manual sampling and lab costs.
- Low reagent consumption and reduced maintenance lower operating expenses and downtime.
- Fast, automatic operation with robust data retention improves decision-making and incident response.
- Accurate and repeatable results support reliable reporting for wastewater, industrial discharge, and surface-water management.
Product Advantages
- Lower failure rate and maintenance demand compared with similar analyzers due to optimized mechanical and reagent systems.
- High measurement flexibility (wide dynamic range up to 500 mg/L) and configurable timing settings to suit diverse water matrices.
- Enhanced dosing accuracy (photoelectric metering) over peristaltic-only systems, and corrosion-protective designs that extend component life.
- Automated recovery behaviors (automatic discharge of residual reactants after fault/reset) increase instrument uptime.
Application Scenarios
- Continuous online monitoring at wastewater/sewage discharge points and industrial effluent outlets.
- Surface water and river monitoring for environmental protection agencies.
- Wastewater treatment plants and process control in industrial facilities (chemical, food & beverage, power, etc.).
- Aquaculture, large-scale municipal water systems, and research or pilot plants requiring unattended TN data.
