  • Wrks really well

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    -Works really well, very precise
    -Also has temperature and humidity sensor
    -Auto turn-off saves batteries
    -Calibrate it using a buffer solution (Not included) or distilled water at pH 7.0-7.1pH
    -Glass electrode

    Cons:

    -You HAVE to calibrate it every time you use it. Otherwise, you will get bad readings (not really a con, says it in the manual)
    -Open it slowly so the electrical connections don't get damaged
    -The last pH digit is useless, because the precision it's just +-0.1 PH, so just dont pay attention to it

    OtherThoughts:

    Its a really good tester, looks very professional and works very well. Only for liquids.

    Bottomline:

    You HAVE to buy a buffer solution for calibration ad calibrate every time you use it.
