I got a new ph meter this year, an Apera PH60. Not top of the line but I think it's pretty good. It has 3 point calibration but I typically just do 2 point because I only ordered the 7.0 and 4.0 liquid last time. I calibrate before every batch.
Yesterday I did the 7.0 calibration then took a mash reading(5.75), then did the 2nd point calibration with 4.0 liquid and did another reading(5.35). Is it normal to have that much variance between 1 point and 2 point calibration readings? I'm assuming not and the calibration fluid was not doing it's job? I'm starting to wonder if measuring ph is even worth the hassle unless you have a top of the line meter.
