Hi. I purchased the vivsun ph and ppm meter. The ph meter jumps all over the place and has a different reading each time i test the same solution. I would probably feel safer with a ph drop kit. The ppm meter seems ok.
I do not have time guessing what my ph is. Can someone suggest an accurate alternative? Preferably in amazon. Thank you.
