I have two hydrometers and a refractometer. Here's the question:Using distilled water at 67 deg. Hydrometer #1 reads 1.002 Hydrometer#2 reads dead on 1.000.But when I measured gravity of primary, I got #1 at 1.038, #2 at 1.032 and the refractometer(calibrated to .000 with 67 deg distilled water) reads 1.050.I've tried cleaning the blue glass and the cover bue still get the 1.050. Since there is obviously some malfunction of the spec., would there be anything wrong with adjusting the spec to read 1.032 and frequently cross checking it's reading with the same hydrometer#2. I really do like the ease of using it, but knew something was wrong after 7 days of active fermentation only reading 1.050. Any suggestions?
