2. get the storage solution, and always always always keep the electrode wet with the storage solution, above all whatever you do ...dont let the electrode go dry
I've owned many different ph meters in my life and only one (my tri-meter) has come out the box with the electrode stored in solution. I always wondered why the meter can be manufactured, shipped and sold dry without breaking but once we get them we are suggested to keep it wet. maybe because of salt build up or something.
i've owned a few of the oakton ph meters too. i always clean and store my meters in solution but just like the others, they eventually gave the same err message that the original poster was talking about. i use a cheap milwaukee ph600 now, its been good for a few months but we'll see how that goes, at least i'll have extra cash to buy another one when it eventually breaks.
