Hi,
I got some pH strips to test that my Star San solution stays under 3. I find the strips a little difficult to read (is that orangish color 3 or 4?)
I won't be buying a very expensive meter but I might buy a cheaper one. I am curious if anyone has experience with these $10 Amazon "pen" models.
The cheap models claim 0.1 accuracy. I would be very happy to be accurate within 0.5 pH.
I see people saying you need to calibrate each time and store in a special solution. I don't think I want the extra task on brew day if I can avoid it. I also see that the probes do not last forever, apparently? So I wonder how far off do they get over time?
I have very lax requirements and I'm lazy. I just want an easy to read indication that I'm at or below 3. It's the cheap probe or the paper for me.
Does anyone have experience with the cheap probes? How bad does it get over time?
Thanks for anything you can share.
