Scope

This Standard specifies the electrochemical probe method for the determination of
dissolved oxygen in water.
This Standard is applicable to the determination of dissolved oxygen in surface water,
underground water, domestic sewage, industrial wastewater and saline water.
This Standard can determine dissolved oxygen with a saturation percentage of 0% ~
100% in water and can also determine supersaturated dissolved oxygen above 100%
(20 mg/L).

Summary	This standard specifies the determination of dissolved oxygen electrochemical probe method. This standard applies to surface water, groundwater, sewage, industrial wastewater and brine Determination of dissolved oxygen. This standard Determination of the percentage saturation of 0 % to 100 % of the dissolved oxygen, can measure more than 100% (20mg/L) of the supersaturated dissolved oxygen.
