The Portable Conductivity Dissolved Oxygen Meter is a high-precision, multi-functional electrochemical analysis tool. The conductivity is primarily used in water quality testing (such as drinking water, pure water, surface water, and tap water) to assess salinity and impurity levels, as well as in industrial production for purity monitoring, soil testing, and environmental monitoring. Dissolved oxygen (DO) is mainly used in the research and monitoring of aquatic ecosystems to assess water health, hypoxia status, and in aquaculture management and wastewater treatment.
