    Standard PH Sensor Probe Help

    Hi All,

    Im new to the forum and have bought a profilux 4 with khd and 2 stand alone 2.1 dosers. Im really struggling to sort the ph prob out. No matter how i calibrate either 4ph and 7ph or 7ph and 9ph it always reads 10.50 ph. My khd director gives an actual ph value of 7.1 and dkh of 8.8.

    can anyone tell me were im going wrong please

    Thanks

    Gazzam

    Hello Gazzam,

    First check to see that the pH probe is connected to the correct port on the ProfiLux.
    It should be connected to the ph/redox port as this is the native pH port.

    Second, repeat the calibration steps according to what is provided in the P4 manual and resource guide.
    Make sure to use pH 7 and pH 9 as these are within normal reef range.

    pH 4 and 7 fluids are only used for calibrating the KH Director probe.


    At the end of calibration, let the probe sit in pH 7 and 9 fluid and wait a few minutes to see the end result.

    Hello, I am having this same problem and submitted a ticket. I have fixed my probe per Vinny's instructions above but now what do I do to get the probe I had to swap Ph probe with to work in the port that the PH probe was not working. My ticket is 1026 and the response intervals need to be improved please.
