Description
I bought this in 1997-98 but never used it much. Should still work fine as far as I can tell. I still have the styrofoam insert from the box but misplaced the cardboard box.I no longer have the cleaning cloth but you can order them online and can download the instructions as well.
I am including 3 20ml packets of Hanna Instruments HI 70004 ph Buffer solution.
You know what these sell for new if you are looking at this. Hopefully this will be a good buy for you.
