Wall-mounted Fluorescence Chlorophyll Analyzer
Product Introduction
It detects based on the fluorescence principle. According to the spectral absorption characteristics of chlorophyll a, high-energy LED light source irradiates water, exciting chlorophyll a in water to produce fluorescence of a specific wavelength, and measuring the concentration of chlorophyll a in water. The sensor adopts a fiber-optic structure, with excellent repeatability and stability, and is not easily affected by ambient light. It is equipped with an automatic cleaning brush, which can eliminate bubbles and reduce the impact of dirt on detection, making the maintenance cycle longer.
