Online Chlorophyll/Blue-green Algae Sensor Online Chlorophyll/Blue-green Algae Sensor for Agriculture Manufacturing

Product Overview

1) Product overview

Product Features

- The BH-485-BAG is a digital online chlorophyll / blue-green algae (cyanobacteria) fluorescence sensor designed for continuous water monitoring.

Product Value

- It illuminates water with a specific monochromatic light and measures the characteristic fluorescence emitted by phycocyanin or phycoerythrin; fluorescence intensity is proportional to cyanobacteria concentration.

Product Advantages

- Measuring range: 100 – 2,000,000 cells/mL. Compact, submersible design (37 mm × 220 mm), IP68 protection, standard 10 m cable (extendable to 100 m).

Application Scenarios

2) Product features

- Wide dynamic range for phycocyanin/phycoerythrin (100–2,000,000 cells/mL).

- High accuracy and repeatability (accuracy < ±5%, repeatability ±3%).

- RS485 Modbus RTU communication for easy integration with PLC/SCADA.

- Integrated optical compensation (LED brightness drift correction) and ambient light rejection.

- Excellent turbidity rejection via small sample volume and high-quality optical filters; recommended for turbidity < 50 NTU.

- Materials: SUS316L (fresh water) and Titanium alloy option for seawater.

- Calibration options: deviation and slope calibration. Operates at 0–45 °C and inlet pressure ≤ 0.4 MPa.

3) Product value

- Provides continuous, real?time detection and early warning of harmful algal blooms and cyanobacterial contamination.

- Helps protect public health and drinking water safety, supports regulatory compliance, and reduces risk of service interruptions.

- Enables proactive process control in water treatment and aquaculture, improving operational efficiency and reducing chemical/operational costs.

- Remote, automated monitoring reduces manual sampling labor and enables multi-site networked monitoring.

4) Product advantages

- Robust construction and marine option (titanium) for long-term deployment in varied water environments.

- IP68-rated, compact form factor suitable for inline or submerged installation.

- Strong signal stability through optical compensation and ambient light rejection—accurate readings under varying lighting and deployment conditions.

- Standard industrial communications (RS485 Modbus RTU) and simple calibration for fast system integration and maintenance.

- Wide measurement range and good turbidity tolerance make it suitable for diverse applications from low-level detection to bloom conditions.

5) Application scenarios

- Drinking water treatment plant inlets and raw water intake monitoring.

- Water source protection (rivers, reservoirs, lakes) and surface/landscape water bodies.

- Aquaculture farms for health management and feed/water quality control.

- Coastal and seawater monitoring (use titanium model).

- Industrial/agricultural water management and any deployment requiring online algal/chlorophyll surveillance and early warning.

- Note: when cyanobacteria distribution is uneven, multi-point monitoring is recommended; best performance when turbidity < 50 NTU.
