On-line analyser for trace dissolved oxygen in water quality
Model：ERUN-SZ4-A-A5
Parameter：dissolved oxygen（DO）
ERUN- SZ4-A-A5 water quality trace dissolved oxygen on-line analyser industrial dissolved oxygen analyser adopts fluorescence extraction principle is a new generation of intelligent on-line analyser developed by our company.The electrodes use an optical construction principle for precise measurement and easy maintenance.It is suitable for continuous real-time monitoring of trace dissolved oxygen (ppb level) in water quality such as industrial boiler water and water vapour quality in thermal power plants.
