hydrometer dilemma

The reason for some is as stated in Pzemol's post ( he also posted on care of swing-arms).
I have a $600.00 conductivity meter and still used the swing arm. The are very fast and
easy to use, especially when you have been using them for decades. Many reefers often use
a refract or conductivity meter, just so they can compare it to their swing-arm and use
it.
