I have a sap hydrometer that is calibrated for 38 degrees. Does anyone know if there is a correction factor you can apply to your reading, say if your sap is 34 degrees or 44 degrees?

Beth, I don't know of any calibration, I don't worry about myself, but... if you take a reading of water at the other temps and see how far off 0% it is, I think you would have your answer. Yes I did used to teach science.
Sap density changes very little with temp, so I don't think you have to worry about it at all. You're probably only talking a tenth of a Brix over many degrees.

Thanks! I guess a few degrees doesn't make a huge difference, but I was hoping since my sugar percent has always been poor here. I got a reading of 1.5% a few days ago, on sap just 2 degrees higher than the calibrated temp, and was hoping that it was going to magically change to 3% somehow.
