Product Advantages

- Measurement method: spectrophotometry using a color-forming reaction (TPPS4 indicator) in alkaline conditions; color change is converted to lead concentration.

Application Scenarios

- Range & performance: 0.00–3.00 mg/L; accuracy ≤±10% (≥0.2 mg/L) and ≤±0.02 mg/L (

- Flexible timing: minimum measurement cycle 50 minutes; digestion time adjustable 5–120 minutes; sampling interval 55–9,999 min adjustable; calibration interval 1–99 days.

- Outputs & interface: 4–20 mA (two channels), RS232/RS485; touch-screen display and command input; data saved during alarms and power loss.

- Practical operation: automatic discharge of residual reactants on reset/power-on; recommended indoor ambient +5–28 °C and ≤90% humidity (no dew); monthly maintenance (~30 min).

3) Product value

- Provides continuous, automated, online monitoring of total lead for faster detection and response compared with manual sampling.

- Helps meet environmental protection and heavy-metal monitoring standards through reliable, quantifiable measurements.

- Reduces labor and sampling effort while maintaining data logging and traceability (automatic saving during faults/power-offs).

- Can be used to safeguard water quality wherever lead contamination is a concern, supporting safer aquatic environments including aquarium systems, process water, and wastewater streams.

4) Product advantages

- Built and tested under a scientific quality-management system by Shanghai BOQU Instrument — established R&D and manufacturing experience.

- Good analytical performance (sensitivity, repeatability, stability) with configurable measurement and digestion parameters to suit different water matrices.

- Robust automation features: automatic flushing of residual reagents, alarm handling, and data retention to minimize downtime and manual intervention.

- Multiple communications outputs for easy integration into monitoring/control systems and remote data collection.

5) Application scenarios

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

- Industrial process water and industrial wastewater monitoring and discharge control.

- Environmental protection and regulatory compliance monitoring at treatment plants and environmental stations.

- Safety monitoring for aquarium systems and aquaculture where heavy-metal control is critical (as an added layer of assurance to typical aquarium water management).
