DOS-118A PORTABLE PURE WATER DISSOLVED OXYGEN METER

 

DOS-118A ppb level portable dissolved oxygen meter is electrochemical analyzer of polarographic measuring principle. Measurement of oxygen in the gas, can also measure the dissolved oxygen  in aqueous solution.

The oxygen concentration in the gas (unit%) used for the measurement of grain, fruit, herbs warehouses, tunnel, air defense and naval vessels, also used to measure the pulmonary function of the medicine, power station, metallurgy, chemical and other boiler combustion process oxygen concentration in the gas phase.

Dissolved oxygen (unit mg/L) is dissolved in water or liquid molecular oxygen, its content is an important indicator of water quality merits. The measurement of dissolved oxygen is the indispensable monitoring project of power generation, boiler, aquaculture, water protection, water supply, sewage treatment and other departments.
