TDS PH Meter Digital Water Tester:our focus is to provide you with the ultimate experience through exceptional service. Just got this today and when I took the tip off of the pH reader there was a clear liquid in the cap as if someone had returned it after using it but never dried it off. I am aware of the instructions notating there may be some crystallization, but they said nothing about how there may be a clear liquid, especially in this amount, about a 1/4 teaspoon of a mysterious clear liquid with a weird smell. Being these are from China and this Coronavirus is going around, I was unable to use this after I had set out all my other materials for my project.finally popular brand,max 45% off,washington mallTDS PH Meter Digital Water Tester
