The only reason I use a hydrometer these days is so that I have an excuse to use some of the beer and taste a bit more afterwards.

I guess the biggest problem is that it seems to always stick to the side of the thief. I've tried using various amounts of a sample, I spin it, etc. etc. but the readings seem to bounce all over the place. Now the hydrometers have wider bases which seem to only increase the problem.

Try to find a dead level surface, or adjust the base by putting card under it on one side until you find a level.

I've never tried it in a thief. You might have better luck with a cylinder.

+1 on this...volume is NOT necessary for specific gravity simply to know where your wort is at and the ABV...

Just stick a thermometer in there to find the temp. Google search for "hydrometer temperature calibration" for the actual numbers to add(/subtract) if your hydrometer didn't come with a chart.

Btw, I picked up a great hydrometer test cylinder a week or so ago for three bucks. I was helping some friends pick up some furniture from Ikea, and they had flower vases there that are just about perfect, other than not being deep enough for my hydrometer to read below about 1.009.

And as always, not all Hydrometers are calibrated at 68F, a good deal are at 60F.

And not all hydrometers are calibrated to read at the bottom of the meniscus. Mine is calibrated to 68F and to be read at the upper meniscus.

Moral of the story---Read the instructions that came with the hydrometer.
