TracWater TW-4729A Online Chlorophyll Sensor

Model number: TW-4729A
Power: 0.2W
Dimension: Φ22mm*175.5mm
Customise: OEM, ODM

Product description:
TracWater TW-4729A online chlorophyll sensor adopts fluorescence method measuring principle. It is widely used in the monitoring, investigation and research of algae and phytoplankton conditions in rivers, lakes, ponds, marine surveys, aquaculture, drinking water sources and other scenes.

Overview

TracWater TW-4729A Chlorophyll Sensor adopts the fluorescence method to measure chlorophyll a concentration in water. By leveraging the spectral absorption characteristics of chlorophyll a, it emits high-energy LED light to excite chlorophyll molecules, which subsequently emit fluorescence at a specific wavelength. Its compact and lightweight design renders it highly suitable for field applications.

Features

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

​

  • Requires no electrolyte, exhibits strong resistance to interference, and eliminates the need for frequent calibration.

​

  • Utilises advanced fluorescence sensing technology for precise measurements.

​

  • Incorporates a sapphire material optical structure, ensuring stable performance under various conditions.

​

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