Blue-green algae monitor in water

Product Introduction:

Holder Electronics HD-YL202 online monitor for blue-green algae in water uses the principle of fluorescence method. Compared with the traditional manual counting method, it is more efficient and faster, and can monitor online in real time. The sensor has better repeatability and stability. It is equipped with an automatic cleaning brush to eliminate bubbles and reduce the impact of contamination on measurement, making the maintenance cycle longer and maintaining excellent stability even in long-term online use. It can serve as an early warning for the reproduction of algae.

Sensor features:

1. Digital sensor, RS-485 output, supports MODBUS

2. With automatic cleaning brush to prevent contamination and remove bubbles

3. Direct measurement, simpler than traditional manual counting method

4. Online continuous monitoring, real-time control of water quality dynamics
