how about in cell culture and fermentation?

Hello everyone, I am new in the forum and I am looking forward to learn a lot from here. My native language is spanish, so correct me, and ask me to rephrase if needed. Here´s the question: I got two different pH sensors that are calibrated with the same calibration solutions. However, when measuring the same solution the difference in measures is approximately 0,2. for example: -Phosphate buffer measured with pH sensor 1: 4,74 -Same Phosphate buffer measured with pH sensor 2: 4,90 Is this difference a big deal? Why is it caused? can I fix it? many thanks
