Looking for PPM Meter


Well-Known Member
I use a Blue Lab pH pen as well, I use a couple cheap-o’s for my ppm meter. The first cheap one I bought lasted forever and did it’s job accurately so I never felt the need to invest in a high quality one. I cannot say the same for the cheap pH pens, I definitely recommend investing in a nice instrument for checking your pH. I picked up my Blue Lab for about $90, but whatever one you get make sure to buy plenty of calibration and storage solution to go along with it.
