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
