i did bought an PH tester.... i don't know if i'm using it correctly, but it does show nothing! It remains standard, i mean 7!
Have one of those myself, works fine. Shine the probe up good with some sandpaper and stick it deep. Lol, ... didn't think mine worked either but I checked it against my electronic one in different solutions. They both gave the same readings.
Give it about 3 minutes for the needle to settle
