Review on ๐ High-Precision Digital PH Meter for Accurate Testing: Pocket-Sized Water Quality Tester, PH Range 0-14, Ideal for Drinking Water, Aquariums, Swimming Pools, Hydroponics by Heather Bell
Garbage. Won't calibrate
I've followed the instructions on T and the pH meter just won't calibrate. I've been doing this for half an hour or more and the pH meter keeps resetting. I washed the electrode with distilled water, dried it and immersed it in a 6.86 calibration solution, but the device does not adjust for calibration. It fluctuates from 30 seconds to a minute and finally the counter shows only zeros. I've tried this with all three solutions and the same thing happens. The thing is junk. Buy another better quality pH meter.
- Sturdy construction
- Sad packaging
