    I bought myself a SAGA PH Pen. I'm reading through the calibration instructions and it says to clean or rinse the electrode first in fresh and then in distilled water between the two buffering steps.

    For this application, will 0 TDS RO water work the same as distilled water? I've read up on the differences between the two types of purification, but I'm not sure if the differences matter here.

    Thanks

    Thanks, good to know. I have an RO filter, so it makes it much easier.
