Reagents: 300 Dissolved Oxygen tests
The Hanna Instruments-93732-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements.
The method is an adaptation of the Standard Methods for Examination of Water and Wastewater, 18th edition, azide modified Winkler method.
The reaction between dissolved oxygen and the reagents causes a yellow tint in the sample. By simply adding the reagents to the sample, a reaction will take place and a compatible benchtop or portable meter can be used to determine the concentration from the colour that is produced.
The results will be displayed in mg/L (ppm) of dissolved oxygen.
These reagents are designed to be used with samples that have an expected range of 0.0 to 10.0 mg/L dissolved oxygen.
