You can easily calibrate for most errors and use a low cost hydrometer to get a high quality reading. Procedure: Keep a trial jar with water near your brew. The idea is that this water have the same temperature as your brew. Before using your hydrometer (every time!): Check the reading of the water. It should be around 1000 s.g. (0 on some hydrometers) but it will vary depending on temperature and scale errors. If your hydrometer shows, say 1002 (+2) you obviously need to take your reading minus 2 to get it right. Then simply take all your wine/beer readings minus 2 and thats it! Similarly of course, if your hydrometer shows 997 (-3) on the water - just add 3 to all your readings. Remember that you have to check the water reading every time because temperature might have changed and/or your hydrometer scale might have moved inside the hydrometer. |
