Product Details
DS430 Chlorophyll Fluorescence Sensor RS485 Chlorophyll Probe
Sensor
Description
The fiber-optic chlorophyll sensor adopts the principle of the
fluorescence method. According to the spectral absorption
characteristics of chlorophyll a, the water body is irradiated by a
high-energy LED light source, and the chlorophyll a in the water
body is excited to generate fluorescence of a specific wavelength,
and the concentration of chlorophyll a in the water is measured.
The sensor's fiber-optic structure provides excellent repeatability
and stability and is less susceptible to ambient light. With
automatic cleaning, the brush eliminates air bubbles, reduces the
impact of contamination on the measurement, makes the maintenance
cycle longer, and maintains excellent stability for long-term
online use.
Feature
* Digital sensor, RS-485 output, support MODBUS.
* Automatic cleaning brush to prevent contamination and eliminate
air bubbles
* Direct measurement is easier than traditional analysis methods
* Continuous online monitoring and real-time control of water
