I just bought this and calibrated and tested my wine. The instructions say when the hour glass stops appearing, that is when you take your reading. So in my case the reading at that point was 3.40. The PH continued to fall after that to 3.28. I called the company and they said that I should go with the 3.40 reading.
For those that have this device is that correct?
