Review on 📊 Dr.meter PH100 Digital PH Meter - High Accuracy with 0.01 Resolution and ATC - Wide 0-14pH Range - Water Quality Tester for Home, Pool, Juice, Lab, Brewing - Pocket Size by Ann Coleman

I would give five stars but the temp setting didn't change from c to f but as for the PH it was great for a second a calibration. I will use my finger to check the water temp for my green kids but Fahrenheit would be fine. The first time he tested correctly with General Hydroponics 7.0 and the rest. The meter went down quickly and didn't fall when I added PH down, it comes back and I fell back to the old $13 I had saved. I can give it another chance, but I ride plants too much to play shoddy games, maybe it was a bad apple at the bottom of the barrel damn it! I will start a new one with a fresh one as they sent me a new one. The new one has just been opened and dried with crystals on the flask, I rinsed with distilled water and bought a probe solution that absorbs as it fills. I will rinse with distilled water, dry my mouth with a hair dryer and use the probe solution in the cap every time! Well, that's if it calibrates properly this time. If it doesn't stay stable or work properly, it's not my fault. I think/hope it will be good, I'll give it a second chance, although the first one damaged my size a lot. I will update the new one again since I have the last one, it seems to have a lot of potential but the next update will tell the story of the two meters. lol!
