Let's start with this..
I have a bluelab ph pen and a Oakton eco ph pen I was gifted from a buddy. I calibrate my blue with the 7.01 fluid and it calibrates. I also turned the pH pen (upside down ) to see if the probe was dirty which it wasn't . Buy there was an air bubble within the probe and it arose to the tip of the probe. Could this cause a problem. The reason I say this is. I calibrated the Oakton with the 7.01 and I'm getting a .03 difference on the ph when testing the resivor water.
Is my blue right. Is the Oakton right?
