Test Strips

Do you know if the pH test strips are immersed in an aqueous solution prior to test "air test?"

If they are dry, I'm pretty sure there is testing for air dry samples of pH test strips in vapors. They obviously use a different color chart than aqueous tests, and are less accurate...but what does that matter when related to security theater? It's the mere appearance that you are testing that counts.
