Apex ph probe

[cale0721]

So I recalibrated my probe today bc I saw recommendations to do it every 6 months so I had some calibration fluid packages from brs. How about it was off by a whole 1.0???

I was kind of shocked. Any one else calibrate theirs regularly?

Holy shiitake. Don't calibrate mine regularly, but gonna check it now.....that's for sure.

I just re-calibrated mine last week and it was off a whole 1.0 as well... I try and do it every 3 months or so.

Ya I was pretty bummed when I found out my ph is at 7.9 average

I just recalibrated mine and the pH reading went down from 8.22 to 8.12. A lot less deviation compared to some of you.
