Product Features

1) Product overview

Product Value

- BOQU TPbG-3055 is an online automatic total lead analyzer using spectrophotometry designed to meet national environmental protection standards.

Product Advantages

- It performs continuous, automatic measurement of lead in water by forming a colored complex and converting the color change into a lead concentration reading.

Application Scenarios

- Built for durability and certified to international standards; intended for expanding market demand in environmental monitoring.

2) Product features

- Measurement principle: colorimetric reaction with TPPS4 indicator in alkaline conditions; color change is measured optically.

- Measuring range: 0.00–3.00 mg/L. Accuracy: ≤±10% (≥0.2 mg/L) and ≤±0.02 mg/L (

- Adjustable digestion time (5–120 min); minimum measurement cycle ~50 minutes (adjustable to sample). Sampling interval adjustable 55–9999 min; calibration interval adjustable 1–99 days.

- Outputs: 4–20 mA (two channels), RS232 and RS485. Touch-screen display and command input. Data saved on alarms and power-off. Automatic discharge/resume after reset.

- Environmental/power specs: recommended ambient +5–28 °C, humidity ≤90% (no dew); AC 220 V, 50 Hz; physical size H1450 × W510 × L450 mm.

3) Product value

- Enables continuous online monitoring for regulatory compliance and fast detection of lead contamination in water systems.

- Supports environmental protection programs by providing reliable data for heavy metal prevention and control projects.

- Reduces manual sampling and laboratory turnaround time, improving responsiveness to pollution events and process control.

4) Product advantages

- Automated, hands‑off operation with adjustable measurement parameters to suit various water matrices.

- Stable and repeatable readings with certified accuracy and international approvals; robust construction for long service life.

- Multiple output interfaces for integration with control systems and data logging; built‑in data retention and automatic recovery after power/alarms.

- Low routine maintenance (recommended monthly check, ~30 minutes) and configurable calibration and sampling schedules.

5) Application scenarios

- Continuous monitoring of surface water (rivers, lakes) for lead contamination.

- Online analysis in industrial process water and industrial wastewater streams (e.g., metallurgy, plating, chemical plants).

- Environmental monitoring stations and wastewater treatment plants for regulatory compliance and pollution control projects.

- Process control and early-warning systems where real-time lead concentration data is needed.
