some of the cheap hydrometers also are thermometers. my main criteria is how big is the salinity measurement scale. i have a hard time telling what is the SG when the 1.020-1.030 is a centimeter long.

I had to go to a French site to purchase this (since they were the only ones in Europe that ship worldwide) - https://www.recifart.com/en/water-t...P4*MTc0MDk4NDAxNS4xLjEuMTc0MDk4NDA2Ny4wLjAuMA..
This hydrometer is considered the only one slightly better than the All-Star Tropic Marin hydrometer. Not sure if this is correct but I thought the TM has the lack of temp reference as its main drawback. Maybe not a big deal. I also like that this one comes with a see-through cylinder made for it. All are just minor features, further improving on the fact that hydrometer in general are a better way to measure the most important water parameter, i.e., salinity.
Also, I am getting tired of the Milwaukee refractometer because the last results of been unstable and the latest ICP showed 35.7 PSU while I measured salinity on the same day at 35 - I know @dandemeyere made a comment that his fell out of calibration after some time and it seems as if mine is doing the same. Time for change.
