We used one graduated for antifreeze in one shop I worked at. Since then, I picked up a brewer's model. Graduated in Brix (% of sugars). First thing I did was mix up various antifreeze strengths and make a cheat sheet.
Real glass hydrometers are good too, but I busted on for each batch of beer. Hydrometers were costing more than grains.
