DR-2090 Biological Toxicity Online Analyzer Introduction
The DR-2090 Biotoxicity Online Analyzer uses the luminescent bacteria (Vibrio fischeri) as the online comprehensive monitoring instrument for water quality of the tested organisms, which can directly and objectively reflect the comprehensive toxicity of the water body to the organism (luminescent bacteria), and ensure the supervision mechanism. It can respond quickly to changes in water quality, providing a fast and effective method for comprehensively ensuring water supply safety and environmental supervision, providing early warning for environmental emergencies and monitoring of surface water and drinking water.
