Products Description
Multi-parameter water quality measuring instruments are mainly used on ocean survey ships, ocean buoys, ocean stations and other monitoring platforms to measure various ecological and environmental elements of seawater, including temperature, salinity, conductivity, chloride, depth, dissolved oxygen, turbidity, redox potential, chlorophyll, blue-green algae, etc. These elements can be arbitrarily selected according to actual measurement needs to provide survey data for human health, environmental protection, marine engineering construction, surface aquaculture, marine resource development and marine scientific research.
