Dimension: Φ45mm*190.8mm
Customise: OEM, ODM

Product description:
TW-4727A Self-cleaning Blue-green Algae Sensor adopts fluorescence method, offering a more efficient and faster alternative to manual counting. It enables real-time online monitoring. The TW-4727A with a self-cleaning brush can effectively eliminate air bubbles and minimise contamination, leading to longer maintenance periods.

Overview

​TracWater TW-4727A Blue-green Algae Sensor adopts the fluorescence method, delivering superior efficiency and speed compared to traditional manual counting techniques. It ensures enhanced repeatability and stability while effectively eliminating bubbles and minimising contamination effects on measurements through its self-cleaning brush, thereby extending the maintenance cycle. This enables excellent long-term online stability and provides early warnings for algal growth.

Features

  • Digital sensor with RS-485 output and MODBUS protocol support.

​

  • Employs advanced fluorescence sensing technology, offering greater convenience and efficiency over traditional manual counting methods.

​

  • Water samples require no special treatment, making the sensor ideal for continuous online monitoring.

​

  • Equipped with a cleaning brush to prevent microbial attachment and extend the maintenance interval.

​

  • All calibration data is stored directly in the sensor, enabling on-site installation and immediate use.
