Yes, in the that post I clarified that I have no experience with tropic Marin hydrometers, I assumed that they were talking about swing arm hydrometers, my bad, don't listen to my opinion on tropic Marin hydrometers, all I know is what works for meTo lump swing arm hydrometers into the same sentence as the Tropic Marin glass hydrometer does a serious disservice to both. The TM glass hydrometers are one of the best tools you can use to measure salinity. They are far better than the Milwaukee and its crazy margin of error. The Milwaukee can read 1.025 but actually be anywhere from 1.023-1.027 and be within spec.
I have a Milwaukee and use it regularly but I understand its limits and serious shortcomings.
