Review on π Accurate Water Quality Testing with KETOTEK 2-in-1 PH and TDS Test Meter: Hydroponics, Aquariums, Drinking Water, RO System, Fishponds, and Pools by Jared Perry
1 out of 2 is not good.
PH meter works great. TDS meter not working. When trying to get 600ppm in my hydr system I went from 250. I added more nutrients to 450. I added even more nutrients. to 004. Can't be right and now I have to buy another gauge before I can do anything.
- Useful not only for its intended purpose
- Cord is shorter than other picks
