Chemetrics SO2 Titrets, 10-100 ppm range.
This is a ‘ripper’ test where the sulfite is titrated with an iodide-iodate titrant in acid solution using a starch indicator. The test is rapid, simple and the reagents are stable.
Accuracy is 2-10 ppm; because the test depends on recognizing subtle color differences, this test is more difficult and susceptible to error for red wine. Each kit contains 10 tests.
