Water Quality Blue Green Algae Sensor, 0~300000 cells/ml

Blue-green algae sensors for high-precision water quality monitoring are for sale. Employing a highly sensitive fluorescence measurement principle, they feature an ultra-wide range of 0~300,000 cells/ml and a fine resolution of 1 cell/ml. The water quality sensor delivers linear performance with R² > 0.999, features IP68 protection and a corrosion-resistant housing, and supports RS485/Modbus-RTU protocols for seamless integration into various monitoring systems. 

Feature

• As a water quality sensor for measuring cyanobacteria concentration in water bodies, it employs fluorescence detection technology. Compared to traditional manual counting methods, it offers greater efficiency and speed while enabling real-time online monitoring.
• The sensor incorporates internal filtering algorithms, providing strong resistance to external light interference. It is suitable for monitoring conditions in rivers, lakes, ponds, marine surveys, aquaculture, drinking water sources, and the status of algae and phytoplankton.
• Measurement Range: 0–300,000 cells/mm³. Features IP68 waterproof rating, suitable for long-term online environmental monitoring.
• RS485 Communication Interface: Modbus-RTU protocol enables seamless connection to computers for monitoring and communication. The blue-green algae sensor supports wide voltage input, operating reliably within 7–30V DC.

Installation

Submersible Installation: Features NPT 3/4" threads compatible with our waterproof tubing. Route the cable through the tubing and screw the device into the waterproof tube's threads.

Note:

1. Install the water quality sensor considering water level fluctuations, ensuring the device remains at least 10 cm below the water surface. Position it in an area with slow-moving water and minimal bubbles.
2. Maintain a 5cm clearance from surrounding walls during sensor installation, with no obstructions within 7cm below the sensor.
