Hi there,
I bought this probe about a year ago. I loved it. I only used it for about 3 or 4 months, then left it in plain tap water for a few months. I didn’t think leaving it in water would hurt it…
I’m trying to calibrate it again but it is reading too high. About 7.5 in PH 7.0 solution. It is only just a year old, and was only ‘probed’ for less than a second every hour or so, (for a few months)…
I tried leaving it in PH 4.0 overnight, that didn’t help. I tried heating the PH solution to 50 degrees, that didn’t help either. I’ve left it in the storage solution now.
(Which I should have done from the beginning and I wouldn’t be having this problem… I suspect… anyway)
Is there a way to save this probe or do I have to buy another one? I thought being an industrial probe, it would be okay sitting in water… As long as it didn’t dry out, I thought I was golden…
Oh well, please advise if there is something I could do to save it.
Also, I’m trying to figure out how to reset the adjustment on the PH Adapter v1.1? I read somewhere you short out the BNC connector on the circuit board and adjust it to read 2.5v on the signal data line. Does that sound right? How can I test if my adapter is okay?
Thanks for the help.
