Oakton pH2.
This fucking pH Tester. This thing has never worked right from day one. I think it's faulty. I keep it in 7.0 solution all the time. From the minute I took it out of the container it has either been being used or been submerged in 7.0 solution.
Here is the problem: I turn the thing on and it will show a very high reading, anywhere from 8.0 to 10.0 (and sometimes even higher). As soon as I turn it on it starts to drift. Sometimes up first, sometimes down. Sometimes up then down. It usually takes about 5-10 minutes to get it to show a steady reading. I understand that you can calibrate it once it normalizes. So it'll show something like 8.2 for example. I press calibrate. You can either wait or press enter to confirm calibration. Either way it almost always yields the same result: ERR (error). Then it returns to displaying whatever wack number it was displaying before. Maybe about 5% of the time I get it out to use it I can suceed in getting it to calibrate correctly if the reading drifts close enough to 7.0. Whether or not it gets close enough seems completely out of my control. Using fresh solution seems to make no difference. Rinsing it off and then trying seems to make no difference.
So this thing was basically an impulse buy. I liked the way it looked and it had some features that I didn't really need but thought they were cool. I use to have a Milwakee pH600, which worked fine. Much quicker to calibrate and didn't drift so much. Now I've accidentally let the Milwakee dry out and I think it's permanently fucked.
Is there something I'm doing wrong with the Oakton? Does anybody else have problems with this thing?
Thank you for reading my post, which was about 90% bitching and 10% legitimate question.
