This test strip is for the rapid and reliable determination of Sulfite in solutions. The easy dip-and-read-procedure provides a reliable result within 20 seconds.
In process and boiler water, sulfite is used as an oxygen scavenger. To avoid over treatment, the concentration needs to be controlled, regularly. These tests are also used to control the Sulfite concentration in foodstuff treated with sulfur compounds (SO₂, HSO₃^-, SO₃^2-) for longer shelf-life. In the process of wine making the control of sulfite is important to control production and quality of the wine.
