To be honest, this looks like a spam setup post, but I'll play along for now.*

At PF, we require users to do their own research before posting questions here. So what have you found in your searching so far?

Maybe @berkeman made the right guess. Otherwise, did you try checking with merchants of pH meters? Is your question based on interest from your education, your experience, or a hoped-for application? I am strongly guessing that pH measurement would only have meaning for water-based blend or mixture or solution. Or maybe for some water dispersed in non-aqueous materials. Experts could respond.

So I googled the question and found an interesting article quite easily.
Let's wait to the OP tells us what research they have done first.
