Aeration Oxidation Apparatus for Testing Free SO2 in wine winemaking

Description

Testing kit for Free (Unbound) Sulfer Dioxide in Wine using the Aeration Oxidation in Wine.
This was purchased a number of years ago from Presque Island (piwine.com).
This kit has the aqua pump so does not have sink adapters.
I have never used this so I can't provide any tips. Printed out instructions from Presque Island (piwine.com) are included.
This kit is similar to this one: https://www.piwine.com/aeration-oxidation-apparatus-free-so2.html
This does not come with any reagents/chemicals for testing your wine. You will need to purchase those on your own.
