Had the exact same problem with my Hanna stick. Been using it for months, reading 1.026, had some issues and took my water to a LFS for testing, they read 1.029!! Got a refractometer after that. Even after calibration the Hanna still reads 0.002 lower than refractometer
I am highly recommending the Tropic Marin Hydrometer for exactly the reasons you pointed out. Under normal temperatures, the Hydrometer can't be wrong, I use it to calibrate my Hanna.
Very nice, I'd been looking at those floaties and other salt checkers for a while, watching you go through all that is enough to get it out of my system 🙂 I'm not a fan of taking refractometer readings w/o my glasses... my cheesy cheep salt probe has matched the refractometer for a year now, I'm almost afraid to recalibrate them🙃
You should put the Hanna calibration fluid in your sump to match the temp first then calibrate outside. Also cleaned the sensor too. Then you should be on point.
Nothing beats the Milwaukee refractometer, my buddy runs a big shop and thats what he uses!

Nice experiment. Clever to recalibrate from the known tank water.
Thanks Ed

🤣😂😅 I just re-read the title, been a while shaggy...
I have a touch of mac degen in my eyes so trying to use a manual refractometer is out, I thought the Hanna was the answer, guess not.

I'll try it, thanks
