    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.
    Kelway pocket size soil tester needs no chemicals - simply insert in soil for instant reading!
    Push button switch for measuring pH ranges from 3.5 to 8. Can be calibrated to maintain accuracy. Also measures soil moisture. Accuracy +/- .2 pH in acidic soils. Not designed for alkaline soils of 7.5+ pH or greater. Case included, 6 1/2in. long.
