This is one of two kits we are offering which do not comply with the original aim of this project; that of having inexpensive kits which enable the user to produce lab quality results with no technical skills. This kit is comparatively expensive but it does meet the other criteria, giving accurate results without specific technical skills.
The level of dissolved oxygen in natural waters is often a direct indication of quality, since aquatic plants produce oxygen, while microorganisms generally consume it as they feed on pollutants.
To perform a test Place the CHEMet ampoule, tip first, into the sampling tube. Snap the tip. The ampoule will fill leaving a bubble for mixing. Gently invert the ampoule several times, allowing the bubble to travel from end to end. Dry the ampoule. Test results should be obtained within 30 seconds after snapping the ampoule. Obtain a test result by gently placing the ampoule, flat end first, into the comparator. Hold the comparator up toward a source of light and view from the bottom. Rotate the comparator until the best color match is found.
