I was excited to try my new refractometer, Hanna Instruments Hi96811, to measure my Oatmeal Stout. I calibrated with distilled water and then checked reading again and got a reading of 0.0. I then checked my stout and got a brix of 8.0. This device has auto temp control and when converted to SG, that's 1.032.
I then checked my stout with my hydrometer. Temperature adjusted SG was 1.017. I checked my hydrometer with distilled water and it adjusts to .997 so not quite 1.00 as it should be but not a huge discrepancy.
What am I doing wrong?? I would not expect a difference of 1.032 to 1.017! And yes, I know how to read a hydrometer.
Thanks in advance
