My hydrometer is about 9 points off. It measures bottled water at 0.990~0.991 at ~60*F. What the heck! I have been using it for 3 batches now. This screws everything up. Anyone else have this problem?
Many have that problem. Mine reads 4 over, just have to remember to adjust every reading and to check/calibrate every so often just to make sure things have stayed the same.
This happened to me, although not as badly. Mine was about 2 points low after a year or so of use. I think the paper inside slid down from repeatedly dropping it down into the empty hydrometer tube. I'm more gentle with them now...
I just took a closer look and the paper inside had come loose from the little bit of red glue that held it in place. I "recalibrated" it by tapping it on some newspaper on my counter. Piece of crap.
