DOS - 118B Industrial Water and Gas Portable Oxygen meter
DOS - 118A is polarography principle of electrochemical analysis instrument.Measuring gas of oxygen, but also dissolved oxygen in water solution.
Gas oxygen concentration (%) of measurement used in the food, fruit, medicinal materials warehouse, tunnels, civil air defence fortifications, ships, and lung function measurement is used in medical,
power station, metallurgy, chemical industry and so on boiler combustion process of gas phase oxygen concentration measurement.
Dissolved oxygen (mg/L) refers to dissolve in water or liquid oxygen molecule state, its content is aquaculture, water conservation, water supply,
sewage treatment and other departments of the indispensable monitoring project.
