Brand: Erun
Name：On-line circulating cooling water quality analyser
Model: ERUN-SZ
Detection parameters: pH, dissolved oxygen, conductivity, turbidity, suspended solids, total hardness
ERUN-SZ series on-line circulating cooling water quality analyser,It is capable of comprehensively detecting a number of water quality parameters including pH, dissolved oxygen content, conductivity, turbidity, suspended solids concentration, total hardness, chloride ion content, total iron content, copper ion concentration, oil content, free chlorine concentration, NH3-N concentration and chemical oxygen demand (COD).In addition, the analyser supports optional detection of parameters such as full alkalinity and silica to meet a wider range of needs.
It has a wide range of applications covering steelmaking, ammonia production, thermal power plants, foundry industry, steel rolling production, blast furnace and converter operations, petroleum refining and other industries, and is suitable for continuous and real-time on-line monitoring and analysis of a variety of circulating cooling water systems, such as inter-cooled open-ended circulating cooling water, direct-cooled open-ended circulating cooling water, as well as inter-cooled closed-ended circulating cooling water, and other circulating cooling water systems.
