Ph tester for solids

    Hello everyone,

    First of all thank you for your help.

    I'd like to know if there are any ph testers for solids not diluted and where can I buy them and how much would they cost.

    Thanks!

    What does the pH of a solid mean? A measure of the pH only makes sense for an aqueous solution.

    I'm studying a project in which we are trying to measure the ph of a tooth in order to detect a carie. That's why we'd like to get a ph tester for solids

    Ok, so you're not measuring the pH of a solid, but the pH of a solution coating the solid.

    I can't help you further, but hopefully some others can.
