While looking thru the AIH website during their sale, I considered purchasing some buffer solution for my pH meter. Noticed the following in the Q&A
"Q: I'm new to ph testing. Do I need to always calibrate my meter using both the 4.0 and 7.0 buffer solutions or can just use one to accurately calibrate?
Asked by: NA Ben - 3/20/2017
A: You can use one or the other, depending on which range your looking to test

Gets me thinking. If we're testing our mash pH, why do we need to calibrate at both 4 and 7?
Thanks.
