BOQU Cod Analyzer Cod Analyzer High Qualtiy-1

Product Overview

1) Product overview

Product Features

The BOQU TNG-3020 Online Total Nitrogen Analyzer is a factory-built, online instrument for continuous measurement of total nitrogen (TN) in water. It uses resorcinol spectrophotometry, accepts direct water sampling without pretreatment, and covers a maximum range up to 0–500 mg/L TN (multiple configurable ranges). The unit is designed for indoor installation and provides touch-screen control, data retention on alarms or power loss, and outputs via 4–20 mA, RS232 and RS485.

Product Advantages

- Resorcinol spectrophotometry detection with configurable measuring ranges (0–10, 0.5–100, 5–500 mg/L).

Application Scenarios

- High sensitivity and stability: ±0.05 mg/L accuracy at low concentrations and repeatability ≤±5%; stability ≤±10% over 24 hours.

- Automatic online sampling (no pretreatment) and adjustable digestion time (5–120 min) and sampling/calibration intervals.

- Precise reagent metering via visible photoelectric system (small dosing, ~1.5 ml per dose) and selective valve timing.

- Sealed high-temperature/high-pressure digestion, negative-pressure peristaltic pumping with air buffer, and PTFE reagent tubing to reduce clogging and corrosion.

3) Product value

- Enables reliable, continuous monitoring of total nitrogen for regulatory compliance, process control, and environmental protection.

- Reduces operational costs through low reagent consumption, lower maintenance needs, and fewer failures.

- Improves data integrity and uptime with automatic residual-reactant discharge, data retention on faults/power loss, and remote output options for integration into control systems.

- Simplifies field operation by allowing direct immersion sampling and touch-screen operation.

4) Product advantages

- Independently developed instrument with proprietary IP and world-class design emphasis.

- Lower failure rate and maintenance burden compared with similar analyzers due to robust mechanical design (sealed digestion, durable PTFE tubing).

- Accurate, repeatable reagent dosing (photoelectric metering) that avoids peristaltic tube wear errors and minimizes reagent usage.

- Corrosion protection strategies (negative-pressure pumping, air buffer) extend component life.

- Flexible configuration (measurement/calibration/maintenance intervals) and industry-standard communication outputs.

5) Application scenarios

- Online automatic monitoring at wastewater discharge points (municipal and industrial effluents).

- Surface water quality monitoring for rivers, lakes and reservoirs.

- Environmental monitoring stations and regulatory compliance testing.

- Process control in water and wastewater treatment plants and industrial facilities where TN monitoring is required.
