Anyone know of any good hydrometers? The one that i have is not working. I don't think. do you have to caliberate them. Like do you have to let water sit in them for a while? Everytime i use it i get a different reading. Sometimes it will say 1.024 and sometimes it goes off the chart. Like more than 1.030. I don't htink it is right.
