My son has a new science project for his chemistry class. He and four other students are to conduct acidity and alkaline level tests on different water sources. Not knowing how and where to buy meters for this, I searched for ph meters online. I managed to find some. I quickly ordered the more affordable ones. They were delivered a couple of days late. My son and his classmates couldn’t wait to use them.
