  • Works very well, simple to use

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

    Pros:

    -Works very well
    -Good quality of construction
    -Simple to use, just one button!
    -Has a Calibration screwdriver and Included calibration solution (very usefull)
    -Batteries last a very long time

    Cons:

    - You HAVE to calibrate it as soon as you get it, the standard calibration is very off-point. Not really a problem since you have the solution and the screwdriver
    -ppm measure in the hanna scale, see below for the formula to convert to uS/cm

    OtherThoughts:

    Bottomline:

    It's a really good TDS tester, in the Hanna Scale, so if you need the standard values, here is the formula:
    (TDS)ppm = Conductivity µS/cm x 0.5
    or
    Conductivity µS/cm = (TDS)ppm / 0.5
    or just look in google a ppm to uS conversion calculator ans put the value "0.5" instead of the normal "0.67"
    Not really a problem
