Used to determine the level of SO2 in your wine. Contains 10 tests in the form of glass titrets. They can be used by themselves or you can purchase W510B which is a titret holder. Please keep in mind that due to some chemical interference, this kit is only accurate to within +/- 30ppm when used to test red wines.
Please note: the box states that this test kit is to be used with white wines only. However, we have found the kit can still be used for red wines as well. Titration tests are based on chemical reactions that cause a color change in the sample. This color change, which is much more obvious in white wine samples, will be harder to detect when used with red wine samples.
