    What are you using it for?(Testing pool ph or critical lab work.)
    You can usually pick one up cheaper than you can build.
    Scott Welch or Allen Welch makes a variety from a pocket unit to a
    high end table top unit.
    Try going over to the Edmund Scientific site they sell them.
    (I have a small pen type that is extremely accurate that I use for
    testing photo chemicals, also works on my swimming pool. Cost 50.00
    bucks.)

    X-No-Archive: Yes

    Not useful at all without the pH electrode. The most expensive part in this project.

    | I have a nice pocket pH tester sold by Cole Parmer

    My uncle ( a crop biologist ) said pocket ph meters are not
    durable, so I bought & use a pack of 100 strips of
    Universalindikator pH 0 -14 ( made by Merck, in Germany ) :
    work well for colourless fluid, but may be less accurate (
    colours displayed will be darkened ) for dark coloured fluid.
