You'd lose. Hence the term, non-dipping test strips. I've seen these at MKE. They have a small pad on one side that is the testing medium. I've seen them on the floor occasionally, apparently not being disposed of properly.
pH test strips are dipped and react to the pH of the liquid, which is either acidic, neutral, or alkaline.
