Product Details


FDO-99 Online Dissolved Oxygen Analyzer
 Product Introduction


Series FDO-99 fluorescence method dissolved oxygen analyzer, is the product which is specially designed for the water environment monitoring and sewage treatment. It adopts the advanced fluorescence quenching principle and accurate phrase detection technology and innovative packaging process, which makes its reliability and service life leading the rival product greatly. Its unique characteristics of long-term low drift and maintenance-free make the product surpass and take the place of traditional membrane electrode completely.
