Digital pH Meter for Water, pH Tester for Hydroponics

****

I just bought this as an upgrade to the liquid drop pH tester that came with the pH up and down kit. I've only used it once but I like the accuracy! My little one will likely use it to be more accurate in her next plant based science project.
