Dissolved oxygen test kit

The Hanna dissolved oxygen portable test kit can determine the oxygen concentration in water quickly and easily.

The chemical test kit allows up to 110 tests of Dissolved Oxygen to be taken from 0.0 to 10.0mg/L with 0.1mg/L resolution.

Manganous ions react with oxygen in the presence of potassium hydroxide to form a manganese oxide precipitate. An azide is present to prevent any nitrite ions from interfering with the test. On addition of acid, manganese oxide hydroxide oxidizes the iodide to iodine. Since the amount of iodine generated is equivalent to the oxygen in the sample, the concentration of iodine is calculated by titration of thiosulfate ions that reduce the iodine back to iodide ions.
