BOQU Nitrogen Analyzer From China

Product Overview

1) Product overview

Product Features

- The TZnG-3056 is an online, automatic total zinc analyzer from Shanghai BOQU (presented alongside BOQU’s nitrogen analyzer product line).

Product Value

- It uses an optical (spectrophotometric/colorimetric) method with on-board acid digestion and oxidation to convert all zinc species into a colored complex that is measured and reported as total zinc concentration.

Product Advantages

- Designed to meet national environmental protection standards for continuous heavy‑metal monitoring in water.

Application Scenarios

2) Product features

- Measuring range: 0.00–3.00 mg/L.

- Accuracy: ≤±10% (when ≥0.2 mg/L); ≤±0.02 mg/L (when

- Flexible digestion/measurement timing: minimum measurement cycle ~50 minutes; digestion adjustable from 5 to 120 minutes to suit sample matrices.

- Sampling interval adjustable (55–9,999 min) and calibration interval adjustable (1–99 days). Monthly routine maintenance (~30 minutes).

- Outputs and communications: two 4–20 mA outputs plus RS232/RS485. Data saved during alarms and power loss. Touchscreen for control and commands.

- Environmental/power/size: recommended +5–28 °C, humidity ≤90% (no dew); AC220 V power; dimensions H1450 × W510 × L450 mm.

- Automatic rinsing/discharge of residual reagents after reset or power cycle and automatic resume of operation.

3) Product value

- Provides continuous, real‑time monitoring of total zinc, enabling rapid detection of exceedances and supporting regulatory compliance.

- Reduces need for frequent manual sampling and lab analyses, saving time and operating costs.

- Adjustable digestion and measurement settings allow reliable results across different water qualities and industrial processes.

- Robust data logging and communication outputs facilitate integration with process control or environmental monitoring systems.

4) Product advantages

- Full on-line automatic workflow (acid digestion → oxidation → color development → optical detection) for true total zinc measurement.

- High measurement flexibility (adjustable digestion time, sampling and calibration intervals) for diverse applications.

- Good analytical performance with low detection uncertainty at low concentrations and acceptable repeatability/stability for continuous monitoring.

- Durable, industry-proven design from BOQU with careful material selection and monthly, short maintenance needs.

- Multiple output formats and data retention on alarms/power loss improve reliability and ease of integration.

5) Application scenarios

- Continuous monitoring of surface water, rivers and lakes for environmental protection programs.

- Industrial process water monitoring (chemical, electroplating, metal finishing, smelting, mining).

- Industrial wastewater discharge monitoring and treatment plant effluent control.

- Municipal wastewater treatment plants and environmental monitoring stations requiring heavy‑metal surveillance.

- Any facility or regulatory program requiring online, automated total zinc measurements to meet compliance or process‑control needs.
