hi,
using a calibrated thermometer i tested my 2 hydrometers in 20 degree distilled water. both read 1.003.
i also calibrated my refractometer, also using 20 degree distilled water.
brewed on the weekend, took samples to measure pre boil gravity and OG. I did my readings with the samples at 20 degrees.
hydrometer read:
pre boil- 1044
OG- 1051
refractometer read:
pre boil - 1041
OG- 1048
a difference of .003 between hydro & refracto.
going by my attempt at calibrating my hydro and the same difference of .003 between instruments with my samples, can i assume that my refractometer is accurate and that future hydro readings i just need to subtract .003 to get an accurate reading?
is this what other people do once they calibrate their hydrometers?
i was concerned when BOTH hydrometers read the same 1.003. coincidence or have i done the calibrating testing wrong?
cheers.......
