Our kit may seem more expensive than other kits on the market, but take a look at what they do not include. We have the kit ready to go out of the box ready for testing.
Aeration Oxidation Assembly for Free Sulfur Dioxide w/water aspirator. The vacuum aspiration(aeration-oxidation)method is independent of color or other components, it provides a more correct value for the acid-released free SO2. An aspirator pump that attaches to a lab faucet is included as a vacuum source, but a vacuum pump may also be used.
