Thank you for the question, LaVerne!
To the best of our current understanding, pH is a "chemical abbreviation" and so should be transcribed in UEB in narrative text. See page 4 of the Provisional Guidance for Chemistry Notation Using Nemeth in UEB Contexts (March 2017), which includes the following:
When chemical abbreviations and acronyms appear in narrative context, code switching is unnecessary.
Section 9 of the Braille Code for Chemical Notation deals with abbreviations, and says "Single letters and combinations of letters used as 'shorthand' names of chemical matter are common in chemistry."
