There have been a number of posts regarding inter comparisons of hydrometers with thermometers, other hydrometers and refractometers. If you have a 0-32 Brix refractometer, here is another way.
Dilute one volume of syrup with two volumes of water, all at room temperature. Mix well and read with the refractometer. Following is a table of syrup concentration vs the refractometer reading.
deg Brix----------syrup concentration
21.7-------------------56
24---------------------61
26.3-------------------66
28.7-------------------71
Graph these figures for easy interpolation.
Measure the water first. Be sure your mixture contains ALL of the syrup. You must rinse the measuring container with the mixture.
I use a 10 ml test tube as the measuring device. However, even a 1 ml container provides more than sufficient sample.
