I bought this pH, moisture and light meter at the market a few years ago and have been using it every now and then to check the pH of my soil in pots to make sure they are ok.
I haven't used it for over a year and today when I tried it, the light and moisture function works but the pH is showing the same value all the time.
It's not repairable I believe, and don't think there is a battery in it.
Does anyone had experience with them? Should I just buy a new one?
