I wouldn't trust the hydrometer even if the refractometer is uncalibrated. Get that thing calibrated and toss the hydrometer. Seriously, toss it...
A swing arm hydrometer if matched and marked against a known point of reference at the right temp can be used just fine. In the end our corals can adapt to a wide range of salinity. Keeping salinity at a certain point near 35ppt is the best thing we can do but even if you think you're at 35ppt and you're say 34ppt or 36ppt you'll be just fine keeping it there.
Pick a method to test for salinity, pick a method to calibrate for near the point you want to keep, and pick a method to keep it there. Then keep that consistent.
and personally, I'm not a fan of swing arm hydrometers myself.
