Having a small portable refractometer, I have been measuring and getting figures for the % of water being present in the honey that has been brought into my hot room. Temperature correction has been taken into account to ensure that the reading translated into a valid final figure. BUT, since the refractometer was purchased second hand from a previous beekeeper, I have no evidence that the figures being gained are correct. This being due to the fact that I do not know if the refractometer is correctly set. I need to know if my 18.2% humidity level in my Canola honey is really 18.2%. Is it possible to create a standard medium of known moisture %, one that may be created by the average beekeeper in domestic conditions?
