I have 4 Hanna testers that I no longer have any use for. All checkers have tested and works flawlessly. You will need all new reagents for all of them the reagents that come are expired. I may have some that are still good and if so do I will throw them in. Selling all 4 shipped for $130. I would like to sell as a whole package
